Release Build v2.2.0 (#236)

* fix: resolve cross-platform EPERM permissions errors

modManager.js:
- Switch from hardcoded 'junction' to dynamic symlink type based on OS (fixing Linux EPERM).
- Add retry logic for directory removal to handle file locking race conditions.
- Improve broken symlink detection during profile sync.

gameManager.js:
- Implement retry loop (3 attempts) for game directory removal in updateGameFiles to prevent EBUSY/EPERM errors on Windows.

paths.js:
- Prevent fs.mkdirSync failure in getModsPath by pre-checking for broken symbolic links.

* fix: missing pacman builds

* prepare release for 2.1.1

minor fix for EPERM error permission

* prepare release 2.1.1

minor fix EPERM permission error

* prepare release 2.1.1

* Update README.md Windows Prequisites for ARM64 builds

* fix: remove broken symlink after detected

* fix: add pathexists for paths.js to check symlink

* fix: isbrokenlink should be true to remove the symlink

* add arch package .pkg.tar.zst for release

* fix: release workflow for build-arch and build-linux

* build-arch job now only build arch .pkg.tar.zst package instead of the whole generic linux.
* build-linux job now exclude .pacman package since its deprecated and should not be used.

* fix: removes pacman build as it replaced by tar.zst and adds build:arch shortcut for pkgbuild

* aur: add proper VCS (-git) PKGBUILD

created clean VCS-based PKGBUILD following arch packaging conventions.

this explicitly marked as a rolling (-git) build and derives its version dynamically from git tags and commit history via pkgver(). previous hybrid approach has been changed.

key changes:
- use -git suffix to clearly indicate rolling source builds
- set pkgver=0 and compute the actual version via pkgver()
- build only a directory layout using electron-builder (--dir)
- avoid generating AppImage, deb, rpm, or pacman installers
- align build and package steps with Arch packaging guidelines

note: this PKGBUILD is intended for development and AUR use only and is not suitable for binary redistribution or release artifacts.

* ci: add fixed-version PKGBUILD for Arch Linux releases

this PKGBUILD intended for CI and GitHub release artifacts. targets tagged releases only and uses a fixed pkgver that matches the corresponding git tag. all of the VCS logic has been removed to PKGBUILD-git to ensure reproducible builds and stable versioning suitable for binary distribution.

the build process relies on electron-builder directory output (--dir) and packages only the unpacked application into a standard Arch Linux package (.pkg.tar.zst). other distro format are excluded from this path and handled separately.

this change establishes a clear separation between:
- rolling AUR development builds (-git)
- CI-generated, versioned Arch Linux release packages

the result is predictable artifact naming, correct version alignment, and Arch-compliant packaging for downstream users.

* Update README.md

adds information for Arch build

* Update README.md

BUILD.md location was changed and now this link is poiting to nothing

* Update PKGBUILD

* Update PKGBUILD-git

* Update README.md

* chore: add offline-mode warning to the README.md

* chore: add downloads counter in README.md

* fix: Steam Deck/Ubuntu crash - use system libzstd.so

The bundled libzstd.so is incompatible with glibc 2.41's stricter heap
validation, causing "free(): invalid pointer" crashes.

Solution: Automatically replace bundled libzstd.so with system version
on Linux. The launcher detects and symlinks to /usr/lib/libzstd.so.1.

- Auto-detect system libzstd at common paths (Arch, Debian, Fedora)
- Backup bundled version as libzstd.so.bundled
- Create symlink to system version
- Add HYTALE_NO_LIBZSTD_FIX=1 to disable if needed

-## 🛠️ Building from Source
+### 🪟 Windows Prequisites
+* **Java JDK 25:**
+  * [Oracle](https://www.oracle.com/java/technologies/downloads/#jdk25-windows)

-See [BUILD.md](BUILD.md) for comprehensive build instructions.
+### 🐧 Linux Prequisites
+
+* Make sure you have already installed newest **GPU driver** especially proprietary NVIDIA, consult your distro docs or wiki.
+  * Also make sure that your GPU can be connected to EGL, try checking it first (again, consult your distro docs or wiki) before installing Hytale game via our launcher.
+* Install `libpng` package to avoid `SDL3_Image` error:
+  * `libpng16-16 libpng-dev` for Ubuntu/Debian-based Distro

+  * `libpng` for Arch-based Distro
+
+---
+
+## 📥 Installation
+
+### 🪟 Windows Installation
+
+1. **Prerequisites:** Ensure you have installed all [**Windows Prerequisites**](https://github.com/amiayweb/Hytale-F2P/tree/main?tab=readme-ov-file#-windows-prequisites) listed above.
+2. **Download:** Get the latest `Hytale-F2P-Launcher.exe` from the [**Releases**](https://github.com/amiayweb/Hytale-F2P/releases/latest/) page.
+3. **SmartScreen Note:** Since the executable is currently unsigned, Windows may show a "Windows protected your PC" popup.
+    * Click **More info**, then click **Run anyway**.
+4. **Launch:** Once installed, you can launch the app directly from your Desktop or the Start menu.
+5. **Whitelist in Windows Firewall** [#192](https://github.com/amiayweb/Hytale-F2P/issues/192#issuecomment-3803042908)
+    * Open the Windows Start Menu and search for `Allow an app through Windows Firewall`
+    * Click "Change settings" (you may need Admin privileges) and Locate `HytaleClient.exe` in the list.
+    * Ensure both the Private and Public checkboxes are checked. Click OK to save.
+
+### 🐧 Linux Installation
+
+1. **Prerequisites:** Ensure you have installed all [**Linux Prerequisites**](https://github.com/amiayweb/Hytale-F2P/tree/main?tab=readme-ov-file#-linux-prequisites) above.
+2. **Download:** Choose the package that fits your distribution from the [**Releases**](https://github.com/amiayweb/Hytale-F2P/releases/latest/) page:
+   * **Universal:** `.AppImage`
+   * **Arch Linux:** `.pkg.tar.zst`
+   * **Fedora/RHEL/openSUSE:** `.rpm`
+   * **Debian/Ubuntu:** `.deb`
+3. **Permissions & Execution:**
+   * **AppImage:** Make the file executable and run it:
+     ```bash
+     chmod +x hytale-f2p-launcher.AppImage
+     ./hytale-f2p-launcher.AppImage
+     ```
+   * **Ubuntu/Debian-based or Fedora/RHEL-based:** Install the DEB/RPM:
+     ```bash
+     # Fedora/RHEL-based
+     sudo dnf install hytale-f2p-launcher.rpm
+     # Debian/Ubuntu
+     sudo apt install -y libasound2 libpng16-16 libpng-dev libicu76 # Not needed in v2.2.0+
+     sudo dpkg -i hytale-f2p-launcher.deb
+     ```
+   * **Arch Linux (pacman):** Install the package using:
+     ```bash
+     # Stable Build
+     sudo pacman -U hytale-f2p-launcher.pkg.tar.zst
+     # Development Build
+     yay -S hytale-f2p-git # or
+     paru -S hytale-f2p-git
+     # Manual Build
+     git clone https://aur.archlinux.org/hytale-f2p-git.git
+     cd hytale-f2p-git
+     makepkg -si
+     ```
+
+> [!NOTE]
+> Make sure to adjust the filename correctly with the version and the architecture type. TIP: Use `cd` command to the package location.
+
+### 🍎 macOS Installation  
+
+> [!NOTE]
+> Apple Silicon Users: If you are on an M1, M2, or M3 Mac, you may be prompted to install Rosetta 2 the first time you run the launcher. This is normal and required for compatibility.
+
+1. **Download:** Get the latest `.dmg` file from the [**Releases**](https://github.com/amiayweb/Hytale-F2P/releases/latest/) page.
+2. **Mount:** Double-click the `.dmg` file to open it.
+3. **Install:** Drag the **Hytale F2P Launcher** icon into your **Applications** folder.
+4. **First Run:** If macOS prevents the app from opening because it is from an "unidentified developer":
+    * Open **System Settings** > **Privacy & Security**.
+    * Scroll down to the **Security** section.
+    * Look for the message regarding "Hytale F2P Launcher" and click **Open Anyway**.
+    * Authenticate with your password and click **Open**.
+
+#### **Advanced macOS: Manual Installation (.zip)**
+The `.zip` version is useful for users who prefer a portable installation or need to bypass specific permission issues.
+
+1. **Extract:** Download and unzip the file to your desired location (e.g., `~/Applications`).
+2. **Remove Quarantine:** macOS often "quarantines" apps downloaded via browser. If the app won't open, open **Terminal** and run:
+   ```bash
+   xattr -rd com.apple.quarantine /path/to/Hytale-F2P-Launcher.app
+   ```
+> [!TIP]
+> Type the first part of the command, then drag the app icon into the Terminal window to auto-fill the path.

+
+# 📢 How to Host a Server
+
+## 🌐 Host your Singleplayer Server (Online-Play Feature)
+
+> [!NOTE]
+> You have to play the game to host the server. See Dedicated Server section below if you want to host it without you playing as the host.
+
+1. Open your Singleplayer World
+2. Pause the game (Esc) > select Online Play > Turn on `Allow Other Players to Join` > Set password if needed > Press `Save`.
+3. Check the status `Connected via UPnP`.
+4. If your friends can't connect to your hosted Online-Play feature, please follow **Local Dedicated Server** tutorial.
+
+## 🖧 Host a Dedicated Server
+
+> [!NOTE]
+> If you already have the patched `HytaleServer.jar` in `HytaleF2P/{release/pre-release}/package/game/latest/Server`, you can use it to host local dedicated server. Put the `.bat`/`.sh` script from our Discord server inside your `.../latest/Server` folder.
+
+> [!TIP]
+> Use services like Playit.gg, Tailscale, Radmin VPN to share UDP connection if setting up router as an admin is not possible.
+
+> [!WARNING]
+> `Hytale-F2P-Server.rar` file is needed to set up a server on non-playing hardware (such as VPS/server hosting). Additional: **Linux ARM64** is supported for server only, not client.
+
+> [!IMPORTANT]
+> See detailed information of setting up a server here: [SERVER.md](SERVER.md). Download the latest patched JAR, the patched RAR, or the SH/BAT scripts from channel `#open-public-server` in our Discord Server.

+### "Server" Term and Definiton
+
+"HytaleServer.jar", which called as "Server", functions as the place of authentication of the client that supposed to go to Hytale Official Authentication System but we managed our way to redirect it on our service (Thanks to Sanasol), handling approximately thousands of players worldwide to play this game for free.
+
+Kindly support us via [our Buy Me a Coffee link](https://buymeacoffee.com/hf2p) if you think our launcher took a big part of developing this Hytale community for the love of the game itself. 
+**We will always advertise, always pushing, and always asking, to every users of this launcher to purchase the original game to help the official development of Hytale**. 
+
+### Server Directory Location
+
+Here are the directory locations of Server folder if you have installed 
+- **Windows:** `%localappdata%\HytaleF2P\release\package\game\latest\Server`
+- **macOS:** `~/Library/Application Support/HytaleF2P/release/package/game/latest/Server`
+- **Linux:** `~/.hytalef2p/release/package/game/latest/Server`
+
+> [!NOTE]
+> This location only exists if the user installed the game using our launcher. The `Server` folder needed to auth the HytaleClient to play Hytale online
+> (for now; we planned to add offline mode in later version of our launcher).
+
+> [!IMPORTANT]
+> Hosting a dedicated Hytale server will not need the exact similar tree. You can put it anywhere, as long as the directory has `Assets.zip` which
+> can be acquired from our launcher via our `HytaleServer.rar` server file (which contains patched `HytaleServer.jar`, `Assets.zip`, and `run_server` scripts in `.sh & .bat`.

-## Part 1: Playing with Friends (Online Play)
+# A. Host Your Singleplayer World
+
+This feature is perfect for 1-5 players that want to just play instantly with friends.
+Terms and conditions applies.
+
+## 1. Using Online-Play Feature / In-Game Invite Code
 
 The easiest way to play with friends - no manual server setup required!
+*The game automatically handles networking using UPnP/STUN/NAT traversal.*
 
-### How It Works
+**For Online Play to work, you need:**
-
-1. **Start the game** via F2P Launcher
-2. **Click "Online Play"** in the main menu
-3. **Share the invite code** with your friends
-4. Friends enter your invite code to join
-
-The game automatically handles networking using UPnP/STUN/NAT traversal.
-
-### Network Requirements
-

-
 - **UPnP enabled** on your router (most routers have this on by default)
 - **Public IP address** from your ISP (not behind CGNAT)
 
-### Common Issues
+> [!TIP]
+> Hoster need to make sure that the router can use UPnP: read router docs, wiki, or watch Youtube tutorials.
+>
+> If you encounter any problem, check Common Issues section below!

+2. Select which world you want to play with your friend.
+3. Once you get in the world, press **ESC**/Pause the game.
+4. Press **Online Play** in the Pause Menu.
+5. Set option "Allow Other Players to Join" from OFF to **ON**. You can set Password if you want.
+6. Press **Save**, the Invite Code will appear.
+7. Press **Copy to Clipboard** and **Share the Invite Code** to your friends!
+8. Friends: Press **Servers** in the Main Menu > Press **Join via Code** > Paste the Code > Join.
+
+> [!WARNING]
+> If other players can't join the Hoster with error: `Failed to connect to any available address. The host may be offline or behind a strict firewall.`
+> 
+> **AND ALSO** the Hoster "Online Play" menu shows `Connected to STUN - NAT Type: Restricted (No UPnP)`,
+>
+> this means the Online Play is **unavailable** on the Hoster machine, and it is neccessary to use services to host your world. **We recommend Playit.gg!**

+# B. Local Dedicated Server
+
+This option is perfect for any players size. From small to high.
+
+## 1. Using Playit.gg (Recommended) ✅
 
 Free tunneling service - only the host needs to install it:
 
-1. **Download [playit.gg](https://playit.gg/)** and run it - Connect your account from the terminal (do not close it when playing on the server)  
+1. Go to https://playit.gg/login and **Log In** with your existing account, **Create Account** if you don't have one
-2. **Add a tunnel** - Select "UDP", tunnel description of "Hytale Server", port count `1`, and local port `5520`
+2. Press "Add a tunnel" > Select `UDP` > Tunnel description of `Hytale Server` > Port count `1` > and Local Port `5520`
-3. **Start the tunnel** - You'll get a public address like `xx-xx.gl.at.ply.gg:5520`
+3. Press **Start the tunnel** (or you can just run the Playit.gg.EXE if you already installed it on your machine) - You'll get a public address like `xx-xx.gl.at.ply.gg:5520`
-4. **Share the address** - Friends connect directly using this address
+4. Go to https://playit.gg/download : `Installer` (Windows) or `x86-64` (Linux) or follow `Debian Install Script` (Debian-based only) 
+   * Windows: Install the `playit-windows.msi`

+     * Right-click file > Properties > Turn on 'Executable as a Program' | or `chmod +x playit-linux-amd64` on terminal
+     * Run by double-clicking the file or `./playit-linux-amd64` via terminal
+5. Open the URL/link by `Ctrl+Click` it. If unable, select the URL, then Right-Click to Copy (`Ctrl+Shift+C` for Linux) then Paste the URL into your browser to link it with your created account.
+6. **WARNING: Do not close the terminal if you are still playing or hosting the server**
+7. Once it done, download the `run_server_with_tokens` script file (`.BAT` for Windows, `.SH` for Linux) from our Discord server > channel `#open-public-server`
+8. Put the script file to the `Server` folder in `HytaleF2P` directory (`%localappdata%\HytaleF2P\release\package\game\latest\Server`)
+9. Copy the `Assets.zip` from the `%localappdata%\HytaleF2P\release\package\game\latest\` folder to the `Server\` folder. (TIP: You can use Symlink of that file to reduce disk usage!)
+10. Double-click the .BAT file to host your server, wait until it shows:
+```
+===================================================
+Hytale Server Booted! [Multiplayer, Fresh Universe]
+===================================================
+```
+11. Connect to the server by go to `Servers` in your game client, press `Add Server`, type `localhost` in the address box, use any name for your server.

-## Part 2: Dedicated Server (Advanced)
+# C. 24/7 Dedicated Server (Advanced)
 
 For 24/7 servers, custom configurations, or hosting on a VPS/dedicated machine.
 
-### Quick Start
+## Step 1: Get the Files Ready
 
-#### Step 1: Get the Server JAR
+### Prequisites
 
-The server scripts will automatically download the pre-patched server JAR if it's not present.
+1. `HytaleServer.jar` (pre-patched for F2P players; dual-auth soon for Official + F2P play)
+2. `Assets.zip`
+3. `run_scripts_with_token.bat` for Windows or `run_scripts_with_token.sh` for macOS/Linux
 
-**Option A:** Let the scripts download automatically (requires `HYTALE_SERVER_URL` to be configured)
+> [!NOTE]
+> The `HytaleServer.rar` available on our Discord Server (`#open-public-server` channel; typo on the Discord, not `zip`) includes all of the prequisites.
+> Unfortunately, the JAR inside the RAR isn't updated so you'll need to download the JAR from the link on Discord.
 
-**Option B:** Manually place `HytaleServer.jar` (pre-patched for F2P) in the Server directory:
+> [!TIP]
+> You can copy `Assets.zip` generated from the launcher to be used for the dedicated server. It's located in `HytaleF2P/release/package/game/latest`. 
 
-- **Windows:** `%localappdata%\HytaleF2P\release\package\game\latest\Server`
-- **macOS:** `~/Library/Application Support/HytaleF2P/release/package/game/latest/Server`
-- **Linux:** `~/.hytalef2p/release/package/game/latest/Server`
 
-If you have a custom install path, the Server folder is inside your custom location under `HytaleF2P/release/package/game/latest/Server`.
+## Step 2: Place `HytaleServer.jar` in the `Server` directory
 
-#### Step 2: Run the Server
+* Windows
+  * `%localappdata%\HytaleF2P\release\package\game\latest\Server`
+* macOS
+  * `~/Library/Application Support/HytaleF2P/release/package/game/latest/Server`
+* Linux
+  * `~/.hytalef2p/release/package/game/latest/Server`
+* If you have a custom install path, the Server folder is inside your custom location under
+  * `HytaleF2P/release/package/game/latest/Server`.
+
+## Step 3: Run the Server
 
 **Windows:**
 ```batch
-cd scripts
 run_server.bat
 ```
 
 **macOS / Linux:**
 ```bash
-cd scripts
 ./run_server.sh
 ```
 
-The scripts will:
-1. Find your game installation automatically
-2. Download the pre-patched server JAR if needed
-3. Fetch session tokens from the auth server
-4. Start the server
-
-#### Step 3: Connect Players
-
-Share your server IP address with players. They connect via the F2P Launcher's server browser or direct connect.

+
+**Symptoms:** Singleplayer world fails to load, "Server failed to boot" error.
+
+**Solution - Whitelist in Windows Firewall:**
+1. Open **Windows Settings** > **Privacy & Security** > **Windows Security**
+2. Click **Firewall & network protection** > **Allow an app through firewall**
+3. Click **Change settings**
+4. Find `HytaleClient.exe` and check both **Private** and **Public**
+5. If not listed, click **Allow another app** and browse to:
+   ```
+   %localappdata%\HytaleF2P\release\package\game\latest\Client\HytaleClient.exe
+   ```
+
+### Duplicate mod error
+
+**Symptoms:** `java.lang.IllegalArgumentException: Tried to load duplicate plugin`
+
+**Solution:**
+1. Navigate to your mods folder:
+   ```
+   %localappdata%\HytaleF2P\release\package\game\latest\Client\UserData\Mods
+   ```
+2. Remove any duplicate `.jar` files

+
+## Linux Issues
+
+### GPU not detected / Using software rendering (llvmpipe)
+
+**Symptoms:**
+- Game uses integrated GPU instead of dedicated GPU
+- Very low FPS / unplayable performance
+- Play button not clickable
+- Log shows `llvmpipe` instead of your GPU
+
+**Solution for NVIDIA:**
+```bash
+__EGL_VENDOR_LIBRARY_FILENAMES=/usr/share/glvnd/egl_vendor.d/10_nvidia.json ./HytaleF2P.AppImage
+```
+
+**Solution for AMD (hybrid GPU systems):**
+```bash
+DRI_PRIME=1 ./HytaleF2P.AppImage
+```
+
+**Permanent fix - Create a launcher script:**
+```bash
+#!/bin/bash
+export __EGL_VENDOR_LIBRARY_FILENAMES=/usr/share/glvnd/egl_vendor.d/10_nvidia.json
+export DRI_PRIME=1
+./HytaleF2P.AppImage
+```
+
+**Note:** On some desktop systems with AMD iGPU + dGPU, the GPU selector may be inverted (selecting iGPU actually uses dGPU). Use whichever option works.
+
+### SDL3_image / libpng errors
+
+**Symptoms:**
+- `DllNotFoundException: Unable to load shared library 'SDL3_image'`
+- `libpng` related errors
+- Game crashes on startup
+
+**Solution - Install dependencies:**
+
+**Fedora / RHEL:**
+```bash
+sudo dnf install libpng libpng-devel
+```
+
+**Debian / Ubuntu:**
+```bash
+sudo apt install libpng16-16 libpng-dev libgdiplus libc6-dev
+```
+
+**Arch Linux:**
+```bash
+sudo pacman -S libpng
+```
+
+**Alternative - Replace corrupted library:**
+```bash
+cd ~/.hytalef2p/release/package/game/latest/Client/
+mv libSDL3_image.so libSDL3_image.so.bak
+wget https://github.com/user-attachments/files/24710966/libSDL3_image.zip
+unzip libSDL3_image.zip
+chmod 644 libSDL3_image.so
+rm libSDL3_image.zip
+```
+
+### AppImage won't launch / FUSE error
+
+**Solution:**
+```bash
+# Debian/Ubuntu
+sudo apt install libfuse2
+
+# Fedora
+sudo dnf install fuse
+
+# Arch
+sudo pacman -S fuse2
+```
+
+### Missing libxcrypt.so.1
+
+**Solution:**
+```bash
+# Fedora/RHEL
+sudo dnf install libxcrypt-compat
+
+# Arch
+sudo pacman -S libxcrypt-compat
+```
+
+### Wayland display issues
+
+**Symptoms:** Game doesn't launch, stuck at loading, or display glitches on Wayland.
+
+**Solution - Force X11:**
+```bash
+GDK_BACKEND=x11 ./HytaleF2P.AppImage
+```
+
+**Alternative - Electron Wayland hint:**
+```bash
+ELECTRON_OZONE_PLATFORM_HINT=auto ./HytaleF2P.AppImage
+```
+
+### Steam Deck / Gamescope issues
+
+**Solution 1 - Add custom launch options in Steam:**
+```
+ELECTRON_OZONE_PLATFORM_HINT=x11 %command%
+```
+
+**Solution 2 - Launch from Desktop Mode** instead of Game Mode.
+
+**Solution 3 - Force X11:**
+```bash
+GDK_BACKEND=x11 ./HytaleF2P.AppImage
+```
+
+### Ubuntu LTS-based distros (Linux Mint, Zorin OS, Pop!_OS)
+
+These distributions may have compatibility issues due to older system packages. This is a limitation of the Hytale game client, not the launcher.
+
+**Workarounds:**
+1. Install all dependencies listed above
+2. Try the SDL3_image replacement
+3. Consider using a more recent distribution or Flatpak/AppImage with bundled dependencies
+
+---
+
+## macOS Issues
+
+### "Butler system error -86" (Apple Silicon)
+
+**Symptoms:** `Butler execution failed: spawn Unknown system error -86` (EXC_BAD_CPU_TYPE)
+
+**Cause:** Butler (the update tool) is x86_64 only.
+
+**Solution - Install Rosetta 2:**
+```bash
+softwareupdate --install-rosetta
+```
+
+Then restart the launcher.
+
+### Auto-update fails with code signature error
+
+**Symptoms:**
+```
+Code signature at URL did not pass validation
+domain: 'SQRLCodeSignatureErrorDomain'
+```
+
+**Solution - Manual update:**
+1. Download the latest version manually from [Releases](https://github.com/amiayweb/Hytale-F2P/releases/latest)
+2. Backup your data first (see [Backup Locations](#backup-locations))
+3. Install the fresh download
+
+### "Unidentified developer" warning
+
+**Solution:**
+1. Open **System Settings** > **Privacy & Security**
+2. Scroll to **Security** section
+3. Find the message about "Hytale F2P Launcher"
+4. Click **Open Anyway**
+5. Authenticate and click **Open**
+
+### App won't open (quarantine)
+
+**Solution:**
+```bash
+xattr -rd com.apple.quarantine /Applications/Hytale-F2P-Launcher.app
+```
+
+---
+
+## Connection & Server Issues
+
+### "Failed to connect to server" in Singleplayer
+
+**Possible causes:**
+1. Windows Firewall blocking (see [Windows section](#failed-to-connect-to-server--server-wont-boot))
+2. Patched server JAR download failed
+3. Regional network restrictions
+
+**Solution - Check patched JAR:**
+1. Look for `HytaleServer.jar` in:
+   - Windows: `%localappdata%\HytaleF2P\release\package\game\latest\Server\`
+   - Linux: `~/.hytalef2p/release/package/game/latest/Server/`
+   - macOS: `~/Library/Application Support/HytaleF2P/release/package/game/latest/Server/`
+2. If missing or very small, the download may have failed
+
+**Solution - Regional restrictions:**
+
+Some countries (Russia, Turkey, Indonesia, etc.) may have issues accessing download servers.
+- Try using a VPN for the initial download
+- Once downloaded, the patched JAR is cached locally
+
+### "Infinite Booting Server" / Server stuck loading
+
+**Solution:**
+1. Check if the patched JAR downloaded successfully (see above)
+2. Ensure your GPU meets minimum requirements
+3. Check launcher logs for specific errors
+4. Try with a VPN if in a restricted region
+
+### "Connection timed out from inactivity"
+
+**This is expected behavior.** Sessions have a 10-hour TTL and will timeout after extended inactivity. Simply reconnect to continue playing.
+
+---
+
+## Authentication & Token Issues
+
+### "Invalid identity token" / "Failed to start Hytale"
+
+**Solution:**
+1. **Restart the launcher** - This fetches fresh tokens
+2. **Check system time** - JWT validation requires accurate system time
+3. **Clear cached tokens:**
+   - Delete `config.json` from your HytaleF2P folder
+   - Restart the launcher
+   - Re-enter your username
+
+**Locations:**
+- Windows: `%localappdata%\HytaleF2P\config.json`
+- Linux: `~/.hytalef2p/config.json`
+- macOS: `~/Library/Application Support/HytaleF2P/config.json`
+
+### Token refresh errors
+
+If you see issuer mismatch errors in logs:
+1. Delete `config.json` and `player_id.json`
+2. Restart the launcher
+3. This forces a fresh authentication
+
+---
+
+## Avatar & Cosmetics Issues
+
+### Avatar/skin changes not saving
+
+**This is a known F2P limitation:**
+- F2P mode has no password protection for usernames
+- Anyone can use any username
+- Cosmetics are stored server-side by username
+- If someone else uses your username, they can change your cosmetics
+
+**Workaround:** Use a unique username that others are unlikely to choose.
+
+### Character invisible / Customization crashes
+
+**Solution:**
+1. Use **Repair Game** in launcher Settings
+2. Verify `Assets.zip` exists in your game folder
+3. Clear cached assets:
+   - Windows: Delete `%localappdata%\HytaleF2P\release\package\game\latest\Client\UserData\CachedAssets\`
+4. Restart the launcher
+
+### Avatar creator shows "Offline Mode"
+
+**Cause:** Cannot connect to auth server.
+
+**Solution:**
+1. Check your internet connection
+2. Test connectivity: Open `https://auth.sanasol.ws/health` in browser (should show "OK")
+3. Check if firewall is blocking the connection
+4. Try disabling VPN (or enabling one if in restricted region)
+
+---
+
+## General Issues
+
+### Mods not showing up
+
+**Solution:**
+1. Ensure mods are placed in the correct folder:
+   - Windows: `%localappdata%\HytaleF2P\release\package\game\latest\Client\UserData\Mods\`
+   - Linux: `~/.hytalef2p/release/package/game/latest/Client/UserData/Mods/`
+   - macOS: `~/Library/Application Support/HytaleF2P/release/package/game/latest/Client/UserData/Mods/`
+2. Verify mod files are `.jar` format
+3. Check launcher logs for mod loading errors
+
+### Game updates delete configurations/mods
+
+**This is a known issue being worked on.**
+
+**Prevention - Always backup before updating:**
+- Server configs and worlds
+- Mods folder
+- `config.json` and `player_id.json`
+
+See [Backup Locations](#backup-locations) below.
+
+### Play button not clickable
+
+Usually caused by GPU detection failure. See [GPU not detected](#gpu-not-detected--using-software-rendering-llvmpipe).
+
+**Alternative:**
+1. Go to **Settings** > **Graphics**
+2. Manually select your GPU
+3. Restart the launcher
+
+### Read timeout errors
+
+**Cause:** Network connectivity issues.
+
+**Solutions:**
+1. Check your internet connection stability
+2. Try using a VPN
+3. Check firewall settings
+4. Try at a different time (server load varies)
+
+---
+
+## Known Limitations
+
+### Linux ARM64 not supported
+
+Hytale does not provide ARM64 game client builds. The launcher downloads from official Hytale servers which only provide:
+- Windows x64
+- macOS (Universal/Intel)
+- Linux x64
+
+This is outside our control.
+
+### F2P Username System
+
+- No password protection for usernames
+- Anyone can claim any username
+- Cosmetics shared by username
+- UUIDs generated based on username
+
+A per-player password system is planned for future versions.
+
+### Session Timeout
+
+Game sessions have a 10-hour TTL. This is by design for security.

+# Auto-Updates System
+
+This document explains how the automatic update system works in the Hytale F2P Launcher.
+
+## Overview
+
+The launcher uses [electron-updater](https://www.electron.build/auto-update) to automatically check for, download, and install updates. When a new version is available, users are notified and the update is downloaded in the background.
+
+## How It Works
+
+### 1. Update Checking
+
+- **Automatic Check**: The app automatically checks for updates 3 seconds after startup
+- **Manual Check**: Users can manually check for updates through the UI
+- **Update Source**: Updates are fetched from GitHub Releases
+
+### 2. Update Process
+
+1. **Check for Updates**: The app queries GitHub Releases for a newer version
+2. **Notify User**: If an update is available, the user is notified via the UI
+3. **Download**: The update is automatically downloaded in the background
+4. **Progress Tracking**: Download progress is shown to the user
+5. **Install**: When the download completes, the user can choose to install immediately or wait until the app restarts
+
+### 3. Installation
+
+- Updates are installed when the app quits (if `autoInstallOnAppQuit` is enabled)
+- Users can also manually trigger installation through the UI
+- The app will restart automatically after installation
+
+## Version Detection & Comparison
+
+### Current Version Source
+
+The app's current version is read from `package.json`:
+
+```json
+{
+  "version": "2.0.2b"
+}
+```
+
+This version is embedded into the built application and is accessible via `app.getVersion()` in Electron. When the app is built, electron-builder also creates an internal `app-update.yml` file in the app's resources that contains this version information.
+
+### How Version Detection Works
+
+1. **Current Version**: The app knows its own version from `package.json`, which is:
+   - Read at build time
+   - Embedded in the application binary
+   - Stored in the app's metadata
+
+2. **Fetching Latest Version**: When checking for updates, electron-updater:
+   - Queries the GitHub Releases API: `https://api.github.com/repos/amiayweb/Hytale-F2P/releases/latest`
+   - Or reads the update metadata file: `https://github.com/amiayweb/Hytale-F2P/releases/download/latest/latest.yml` (or `latest-mac.yml` for macOS)
+   - The metadata file contains:
+     ```yaml
+     version: 2.0.3
+     releaseDate: '2024-01-15T10:30:00.000Z'
+     path: Hytale-F2P-Launcher-2.0.3-x64.exe
+     sha512: ...
+     ```
+
+3. **Version Comparison**: electron-updater uses semantic versioning comparison:
+   - Compares the **current version** (from `package.json`) with the **latest version** (from GitHub Releases)
+   - Uses semantic versioning rules: `major.minor.patch` (e.g., `2.0.2` vs `2.0.3`)
+   - An update is available if the remote version is **greater than** the current version
+   - Examples:
+     - Current: `2.0.2` → Remote: `2.0.3` ✅ Update available
+     - Current: `2.0.2` → Remote: `2.0.2` ❌ No update (same version)
+     - Current: `2.0.3` → Remote: `2.0.2` ❌ No update (current is newer)
+     - Current: `2.0.2b` → Remote: `2.0.3` ✅ Update available (prerelease tags are handled)
+
+4. **Version Format Handling**:
+   - **Semantic versions** (e.g., `1.0.0`, `2.1.3`) are compared numerically
+   - **Prerelease versions** (e.g., `2.0.2b`, `2.0.2-beta`) are compared with special handling
+   - **Non-semantic versions** may cause issues - it's recommended to use semantic versioning
+
+### Update Metadata Files
+
+When you build and publish a release, electron-builder generates platform-specific metadata files:
+
+**Windows/Linux** (`latest.yml`):
+```yaml
+version: 2.0.3
+files:
+  - url: Hytale-F2P-Launcher-2.0.3-x64.exe
+    sha512: abc123...
+    size: 12345678
+path: Hytale-F2P-Launcher-2.0.3-x64.exe
+sha512: abc123...
+releaseDate: '2024-01-15T10:30:00.000Z'
+```
+
+**macOS** (`latest-mac.yml`):
+```yaml
+version: 2.0.3
+files:
+  - url: Hytale-F2P-Launcher-2.0.3-arm64-mac.zip
+    sha512: def456...
+    size: 23456789
+path: Hytale-F2P-Launcher-2.0.3-arm64-mac.zip
+sha512: def456...
+releaseDate: '2024-01-15T10:30:00.000Z'
+```
+
+These files are:
+- Automatically generated during build
+- Uploaded to GitHub Releases
+- Fetched by electron-updater to check for updates
+- Used to determine if an update is available and what to download
+
+### The Check Process in Detail
+
+When `appUpdater.checkForUpdatesAndNotify()` is called:
+
+1. **Read Current Version**: Gets version from `app.getVersion()` (which reads from `package.json`)
+2. **Fetch Update Info**: 
+   - Makes HTTP request to GitHub Releases API or reads `latest.yml`
+   - Gets the version number from the metadata
+3. **Compare Versions**: 
+   - Uses semantic versioning comparison (e.g., `semver.gt(remoteVersion, currentVersion)`)
+   - If remote > current: update available
+   - If remote <= current: no update
+4. **Emit Events**: 
+   - `update-available` if newer version found
+   - `update-not-available` if already up to date
+5. **Download if Available**: If `autoDownload` is enabled, starts downloading automatically
+
+### Example Flow
+
+```
+App Version: 2.0.2 (from package.json)
+                ↓
+Check GitHub Releases API
+                ↓
+Latest Release: 2.0.3
+                ↓
+Compare: 2.0.3 > 2.0.2? YES
+                ↓
+Emit: 'update-available' event

+Download update automatically

+Emit: 'update-downloaded' event
+                ↓

+```
+
+## Components
+
+### AppUpdater Class (`backend/appUpdater.js`)
+
+The main class that handles all update operations:
+
+- **`checkForUpdatesAndNotify()`**: Checks for updates and shows a system notification if available
+- **`checkForUpdates()`**: Manually checks for updates (returns a promise)
+- **`quitAndInstall()`**: Quits the app and installs the downloaded update
+
+### Events
+
+The AppUpdater emits the following events that the UI can listen to:
+
+- `update-checking`: Update check has started
+- `update-available`: A new update is available
+- `update-not-available`: App is up to date
+- `update-download-progress`: Download progress updates
+- `update-downloaded`: Update has finished downloading
+- `update-error`: An error occurred during the update process
+
+## Configuration
+
+### Package.json
+
+The publish configuration in `package.json` tells electron-builder where to publish updates:
+
+```json
+"publish": {
+  "provider": "github",
+  "owner": "amiayweb",
+  "repo": "Hytale-F2P"
+}
+```
+
+This means updates will be fetched from GitHub Releases for the `amiayweb/Hytale-F2P` repository.
+
+## Publishing Updates
+
+### For Developers
+
+1. **Update Version**: Bump the version in `package.json` (e.g., `2.0.2b` → `2.0.3`)
+
+2. **Build the App**: Run the build command for your platform:
+   ```bash
+   npm run build:win    # Windows
+   npm run build:mac    # macOS
+   npm run build:linux  # Linux
+   ```
+
+3. **Publish to GitHub**: When building with electron-builder, it will:
+   - Generate update metadata files (`latest.yml`, `latest-mac.yml`, etc.)
+   - Upload the built files to GitHub Releases (if configured with `GH_TOKEN`)
+   - Make them available for auto-update
+
+4. **Release on GitHub**: Create a GitHub Release with the new version tag
+
+### Important Notes
+
+- **macOS Code Signing**: macOS apps **must** be code-signed for auto-updates to work
+- **Version Format**: Use semantic versioning (e.g., `1.0.0`, `2.0.1`) for best compatibility
+- **Update Files**: electron-builder automatically generates the required metadata files (`latest.yml`, etc.)
+
+## Testing Updates
+
+### Development Mode
+
+To test updates during development, create a `dev-app-update.yml` file in the project root:
+
+```yaml
+owner: amiayweb
+repo: Hytale-F2P
+provider: github
+```
+
+Then enable dev mode in the code:
+```javascript
+autoUpdater.forceDevUpdateConfig = true;
+```
+
+### Local Testing
+
+For local testing, you can use a local server (like Minio) or a generic HTTP server to host update files.
+
+## User Experience
+
+### What Users See
+
+1. **On Startup**: The app silently checks for updates in the background
+2. **Update Available**: A notification appears if an update is found
+3. **Downloading**: Progress bar shows download status
+4. **Ready to Install**: User is notified when the update is ready
+5. **Installation**: Update installs on app restart or when user clicks "Install Now"
+
+### User Actions
+
+- Users can manually check for updates through the settings/update menu
+- Users can choose to install immediately or wait until next app launch
+- Users can continue using the app while updates download in the background
+
+## Troubleshooting
+
+### Updates Not Working
+
+1. **Check GitHub Releases**: Ensure releases are published on GitHub
+2. **Check Version**: Make sure the version in `package.json` is higher than the current release
+3. **Check Logs**: Check the app logs for update-related errors
+4. **Code Signing (macOS)**: Verify the app is properly code-signed
+
+### Common Issues
+
+- **"Update not available"**: Version in `package.json` may not be higher than the current release
+- **"Download failed"**: Network issues or GitHub API rate limits
+- **"Installation failed"**: Permissions issue or app is running from an unsupported location
+
+## Technical Details
+
+### Supported Platforms
+
+- **Windows**: NSIS installer (auto-update supported)
+- **macOS**: DMG + ZIP (auto-update supported, requires code signing)
+- **Linux**: AppImage, DEB, RPM, Pacman (auto-update supported)
+
+### Update Files Generated
+
+When building, electron-builder generates:
+- `latest.yml` (Windows/Linux)
+- `latest-mac.yml` (macOS)
+- `latest-linux.yml` (Linux)
+
+These files contain metadata about the latest release and are automatically uploaded to GitHub Releases.

+# Clearing Electron-Updater Cache
+
+To force electron-updater to re-download an update file, you need to clear the cached download.
+
+## Quick Method (Terminal)
+
+### macOS
+```bash
+# Remove the entire cache directory
+rm -rf ~/Library/Caches/hytale-f2p-launcher
+
+# Or just remove pending downloads
+rm -rf ~/Library/Caches/hytale-f2p-launcher/pending
+```
+
+### Windows
+```bash
+# Remove the entire cache directory
+rmdir /s "%LOCALAPPDATA%\hytale-f2p-launcher-updater"
+
+# Or just remove pending downloads
+rmdir /s "%LOCALAPPDATA%\hytale-f2p-launcher-updater\pending"
+```
+
+### Linux
+```bash
+# Remove the entire cache directory
+rm -rf ~/.cache/hytale-f2p-launcher-updater
+
+# Or just remove pending downloads
+rm -rf ~/.cache/hytale-f2p-launcher-updater/pending
+```
+
+## Cache Locations
+
+electron-updater stores downloaded updates in:
+
+- **macOS**: `~/Library/Caches/hytale-f2p-launcher/`
+- **Windows**: `%LOCALAPPDATA%\hytale-f2p-launcher-updater\`
+- **Linux**: `~/.cache/hytale-f2p-launcher-updater/`
+
+The cache typically contains:
+- `pending/` - Downloaded update files waiting to be installed
+- Metadata files about available updates
+
+## After Clearing
+
+After clearing the cache:
+1. Restart the launcher
+2. It will check for updates again
+3. The update will be re-downloaded from scratch
+
+## Programmatic Method
+
+You can also clear the cache programmatically by adding this to your code:
+
+```javascript
+const { autoUpdater } = require('electron-updater');
+const path = require('path');
+const fs = require('fs');
+const os = require('os');
+
+function clearUpdateCache() {
+  const cacheDir = path.join(
+    os.homedir(),
+    process.platform === 'win32' 
+      ? 'AppData/Local/hytale-f2p-launcher-updater'
+      : process.platform === 'darwin'
+      ? 'Library/Caches/hytale-f2p-launcher'
+      : '.cache/hytale-f2p-launcher-updater'
+  );
+  
+  if (fs.existsSync(cacheDir)) {
+    fs.rmSync(cacheDir, { recursive: true, force: true });
+    console.log('Update cache cleared');
+  }
+}
+```

+# Steam Deck / Ubuntu LTS Crash Investigation
+
+## Status: SOLVED
+
+**Last updated:** 2026-01-27
+
+**Solution:** Replace bundled `libzstd.so` with system version.
+
+---
+
+## Problem Summary
+
+The Hytale F2P launcher's client patcher causes crashes on Steam Deck and Ubuntu LTS with the error:
+```
+free(): invalid pointer
+```
+or
+```
+SIGSEGV (Segmentation fault)
+```
+
+The crash occurs after successful authentication, specifically right after "Finished handling RequiredAssets".
+
+**Affected Systems:**
+- Steam Deck (glibc 2.41)
+- Ubuntu LTS
+
+**Working Systems:**
+- macOS
+- Windows
+- Older Arch Linux (glibc < 2.41)
+
+---
+
+## Root Cause
+
+The **bundled `libzstd.so`** in the game client is incompatible with glibc 2.41's stricter heap validation. When the game decompresses assets using this library, it triggers heap corruption detected by glibc 2.41.
+
+The crash occurs in `libzstd.so` during `free()` after "Finished handling RequiredAssets" (asset decompression).
+
+---
+
+## Solution
+
+Replace the bundled `libzstd.so` with the system's `libzstd.so.1`.
+
+### Automatic (Launcher)
+
+The launcher automatically detects and replaces `libzstd.so` on Linux systems. No manual action needed.
+
+### Manual
+
+```bash
+cd ~/.hytalef2p/release/package/game/latest/Client
+
+# Backup bundled version
+mv libzstd.so libzstd.so.bundled
+
+# Link to system version
+# Steam Deck / Arch Linux:
+ln -s /usr/lib/libzstd.so.1 libzstd.so
+
+# Debian / Ubuntu:
+ln -s /usr/lib/x86_64-linux-gnu/libzstd.so.1 libzstd.so
+
+# Fedora / RHEL:
+ln -s /usr/lib64/libzstd.so.1 libzstd.so
+```
+
+### Restore Original
+
+```bash
+cd ~/.hytalef2p/release/package/game/latest/Client
+rm libzstd.so
+mv libzstd.so.bundled libzstd.so
+```
+
+---
+
+## Why This Works
+
+1. The bundled `libzstd.so` was likely compiled with different allocator settings or an older toolchain
+2. glibc 2.41 has stricter heap validation that catches invalid memory operations
+3. The system `libzstd.so.1` is compiled with the system's glibc and uses compatible memory allocation patterns
+4. By using the system library, we avoid the incompatibility entirely
+
+---
+
+## Previous Investigation (for reference)
+
+### What Was Tried Before Finding Solution
+
+| Approach | Result |
+|----------|--------|
+| jemalloc allocator | Worked ~30% of time, not stable |
+| GLIBC_TUNABLES | No effect |
+| taskset (CPU pinning) | Single core too slow |
+| nice/chrt (scheduling) | No effect |
+| Various patching approaches | All crashed |
+
+### Key Insight
+
+The crash was in `libzstd.so`, not in our patched code. The patching just changed timing enough to expose the libzstd incompatibility more frequently.
+
+---
+
+## GDB Stack Trace (Historical)
+
+```
+#0  0x00007ffff7d3f5a4 in ?? () from /usr/lib/libc.so.6
+#1  raise () from /usr/lib/libc.so.6
+#2  abort () from /usr/lib/libc.so.6
+#3-#4  ?? () from /usr/lib/libc.so.6
+#5  free () from /usr/lib/libc.so.6
+#6  ?? () from libzstd.so    <-- CRASH POINT (bundled library)
+#7-#24  HytaleClient code (asset decompression)

+# Steam Deck / Linux Crash Fix
+
+## SOLUTION: Use system libzstd
+
+The crash is caused by the bundled `libzstd.so` being incompatible with glibc 2.41's stricter heap validation.
+
+### Automatic Fix
+
+The launcher automatically replaces `libzstd.so` with the system version. No manual action needed.
+
+### Manual Fix
+
+```bash
+cd ~/.hytalef2p/release/package/game/latest/Client
+
+# Backup and replace
+mv libzstd.so libzstd.so.bundled
+ln -s /usr/lib/libzstd.so.1 libzstd.so
+```
+
+### Restore Original
+
+```bash
+cd ~/.hytalef2p/release/package/game/latest/Client
+rm libzstd.so
+mv libzstd.so.bundled libzstd.so
+```
+
+---
+
+## Debug Commands (for troubleshooting)
+
+### Check libzstd Status
+
+```bash
+# Check if symlinked
+ls -la ~/.hytalef2p/release/package/game/latest/Client/libzstd.so
+
+# Find system libzstd
+find /usr/lib -name "libzstd.so*"
+```
+
+### Binary Validation
+
+```bash
+file ~/.hytalef2p/release/package/game/latest/Client/HytaleClient
+ldd ~/.hytalef2p/release/package/game/latest/Client/HytaleClient
+```
+
+### Restore Client Binary
+
+```bash
+cd ~/.hytalef2p/release/package/game/latest/Client
+cp HytaleClient.original HytaleClient
+rm -f HytaleClient.patched_custom
+```
+
+---
+
+## Environment Variables
+
+| Variable | Description | Example |
+|----------|-------------|---------|
+| `HYTALE_AUTH_DOMAIN` | Custom auth domain | `auth.sanasol.ws` |
+| `HYTALE_NO_LIBZSTD_FIX` | Disable libzstd replacement | `1` |

+# Testing Auto-Updates
+
+This guide explains how to test the auto-update system during development.
+
+## Quick Start
+
+### Option 1: Test with GitHub Releases (Easiest)
+
+1. **Set up dev-app-update.yml** (already done):
+   ```yaml
+   provider: github
+   owner: amiayweb
+   repo: Hytale-F2P
+   ```
+
+2. **Lower your current version** in `package.json`:
+   - Change version to something lower than what's on GitHub (e.g., `2.0.1` if GitHub has `2.0.3`)
+
+3. **Run the app in dev mode**:
+   ```bash
+   npm run dev
+   # or
+   npm start
+   ```
+
+4. **The app will check for updates** 3 seconds after startup
+   - If a newer version exists on GitHub, it will detect it
+   - Check the console logs for update messages
+
+### Option 2: Test with Local HTTP Server
+
+For more control, you can set up a local server:
+
+1. **Create a test update server**:
+   ```bash
+   # Create a test directory
+   mkdir -p test-updates
+   cd test-updates
+   ```
+
+2. **Build a test version** with a higher version number:
+   ```bash
+   # In package.json, set version to 2.0.4
+   npm run build
+   ```
+
+3. **Copy the generated files** to your test server:
+   - Copy `dist/latest.yml` (or `latest-mac.yml` for macOS)
+   - Copy the built installer/package
+
+4. **Start a simple HTTP server**:
+   ```bash
+   # Using Python
+   python3 -m http.server 8080
+   
+   # Or using Node.js http-server
+   npx http-server -p 8080
+   ```
+
+5. **Update dev-app-update.yml** to point to local server:
+   ```yaml
+   provider: generic
+   url: http://localhost:8080
+   ```
+
+6. **Run the app** and it will check your local server
+
+## Testing Steps
+
+### 1. Prepare Test Environment
+
+**Current version**: `2.0.3` (in package.json)
+**Test version**: `2.0.4` (on GitHub or local server)
+
+### 2. Run the App
+
+```bash
+npm run dev
+```
+
+### 3. Watch for Update Events
+
+The app will automatically check for updates 3 seconds after startup. Watch the console for:
+
+```
+Checking for updates...
+Update available: 2.0.4
+```
+
+### 4. Check Console Logs
+
+Look for these messages:
+- `Checking for updates...` - Update check started
+- `Update available: 2.0.4` - New version found
+- `Download speed: ...` - Download progress
+- `Update downloaded: 2.0.4` - Download complete
+
+### 5. Test UI Integration
+
+The app sends these events to the renderer:
+- `update-checking`
+- `update-available` (with version info)
+- `update-download-progress` (with progress data)
+- `update-downloaded` (ready to install)
+
+You can listen to these in your frontend code to show update notifications.
+
+## Manual Testing
+
+### Trigger Manual Update Check
+
+You can also trigger a manual check via IPC:
+```javascript
+// In renderer process
+const result = await window.electronAPI.invoke('check-for-updates');
+console.log(result);
+```
+
+### Install Update
+
+After an update is downloaded:
+```javascript
+// In renderer process
+await window.electronAPI.invoke('quit-and-install-update');
+```
+
+## Testing Scenarios
+
+### Scenario 1: Update Available
+1. Set `package.json` version to `2.0.1`
+2. Ensure GitHub has version `2.0.3` or higher
+3. Run app → Should detect update
+
+### Scenario 2: Already Up to Date
+1. Set `package.json` version to `2.0.3`
+2. Ensure GitHub has version `2.0.3` or lower
+3. Run app → Should show "no update available"
+
+### Scenario 3: Prerelease Version
+1. Set `package.json` version to `2.0.2b`
+2. Ensure GitHub has version `2.0.3`
+3. Run app → Should detect update (prerelease < release)
+
+## Troubleshooting
+
+### Update Not Detected
+
+1. **Check dev-app-update.yml exists** in project root
+2. **Verify dev mode is enabled** - Check console for "Dev update mode enabled"
+3. **Check version numbers** - Remote version must be higher than current
+4. **Check network** - App needs internet to reach GitHub/local server
+5. **Check logs** - Look for error messages in console
+
+### Common Errors
+
+- **"Cannot find module 'electron-updater'"**: Run `npm install`
+- **"Update check failed"**: Check network connection or GitHub API access
+- **"No update available"**: Version comparison issue - check versions
+
+### Debug Mode
+
+Enable more verbose logging by checking the console output. The logger will show:
+- Update check requests
+- Version comparisons
+- Download progress
+- Any errors
+
+## Testing with Real GitHub Releases
+
+For the most realistic test:
+
+1. **Create a test release on GitHub**:
+   - Build the app with version `2.0.4`
+   - Create a GitHub release with tag `v2.0.4`
+   - Upload the built files
+
+2. **Lower your local version**:
+   - Set `package.json` to `2.0.3`
+
+3. **Run the app**:
+   - It will check GitHub and find `2.0.4`
+   - Download and install the update
+
+## Notes
+
+- **Dev mode only works when app is NOT packaged** (`!app.isPackaged`)
+- **Production builds** ignore `dev-app-update.yml` and use the built-in `app-update.yml`
+- **macOS**: Code signing is required for updates to work in production
+- **Windows**: NSIS installer is required for auto-updates
+
+## Next Steps
+
+Once testing is complete:
+1. Remove or comment out `forceDevUpdateConfig` for production
+2. Ensure proper code signing for macOS
+3. Set up CI/CD to automatically publish releases
