+# Code of Conduct
+
+## Our Pledge
+
+We as members, contributors, and leaders pledge to make participation in our community a harassment-free experience for everyone, regardless of age, body size, visible or invisible disability, ethnicity, sex characteristics, gender identity and expression, level of experience, education, socio-economic status, nationality, personal appearance, race, caste, color, religion, or sexual identity and orientation.
+
+We pledge to act and interact in ways that contribute to an open, welcoming, diverse, inclusive, and healthy community.
+
+## Our Standards
+
+Examples of behavior that contributes to a positive environment for our community include:
+
+* Demonstrating empathy and kindness toward other people
+* Being respectful of differing opinions, viewpoints, and experiences
+* Giving and gracefully accepting constructive feedback
+* Accepting responsibility and apologizing to those affected by our mistakes, and learning from the experience
+* Focusing on what is best not just for us as individuals, but for the overall community
+
+Examples of unacceptable behavior include:
+
+* The use of sexualized language or imagery, and sexual attention or advances of any kind
+* Trolling, insulting or derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or email address, without their explicit permission
+* Other conduct which could reasonably be considered inappropriate in a professional setting
+
+## Enforcement Responsibilities
+
+Community leaders are responsible for clarifying and enforcing our standards of acceptable behavior and will take appropriate and fair corrective action in response to any behavior that they deem inappropriate, threatening, offensive, or harmful.
+
+Community leaders have the right and responsibility to remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that are not aligned to this Code of Conduct, and will communicate reasons for moderation decisions when appropriate.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when an individual is officially representing the community in public spaces. Examples of representing our community include using an official e-mail address, posting via an official social media account, or acting as an appointed representative at an online or offline event.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be reported to the community leaders responsible for enforcement at [INSERT CONTACT METHOD]. All complaints will be reviewed and investigated promptly and fairly.
+
+All community leaders are obligated to respect the privacy and security of the reporter of any incident.
+
+## Enforcement Guidelines
+
+Community leaders will follow these Community Impact Guidelines in determining the consequences for any action they deem in violation of this Code of Conduct:
+
+### 1. Correction
+
+**Community Impact**: Use of inappropriate language or other behavior deemed unprofessional or unwelcome in the community.
+
+**Consequence**: A private, written warning from community leaders, providing clarity around the nature of the violation and an explanation of why the behavior was inappropriate. A public apology may be requested.
+
+### 2. Warning
+
+**Community Impact**: A violation through a single incident or series of actions.
+
+**Consequence**: A warning with consequences for continued behavior. No interaction with the people involved, including unsolicited interaction with those enforcing the Code of Conduct, for a specified period of time. This includes avoiding interactions in community spaces as well as external channels like social media. Violating these terms may lead to a temporary or permanent ban.
+
+### 3. Temporary Ban
+
+**Community Impact**: A serious violation of community standards, including sustained inappropriate behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or public communication with the community for a specified period of time. No public or private interaction with the people involved, including unsolicited interaction with those enforcing the Code of Conduct, is allowed during this period. Violating these terms may lead to a permanent ban.
+
+### 4. Permanent Ban
+
+**Community Impact**: Demonstrating a pattern of violation of community standards, including sustained inappropriate behavior, harassment of an individual, or aggression toward or disparagement of classes of individuals.
+
+**Consequence**: A permanent ban from any sort of public interaction within the community.

 ### Creating a Release
 
-1. Update version in `package.json`
+**⚠️ IMPORTANT: Semantic Versioning Required**
+
+This project uses **strict semantic versioning with numerical versions only**:
+- ✅ **Valid**: `2.0.1`, `2.0.11`, `2.1.0`, `3.0.0`
+- ❌ **Invalid**: `2.0.2b`, `2.0.2a`, `2.0.1-beta`
+
+**Format**: `MAJOR.MINOR.PATCH` (e.g., `2.0.11`)
+
+The auto-update system requires semantic versioning for proper version comparison. Letter suffixes are not supported.
+
+**Steps:**
+
+1. Update version in `package.json` (use numerical format only, e.g., `2.0.11`)
 2. Commit and push to `main`
 3. Create and push a version tag:
 
 ```bash
-git tag v2.0.1
+git tag v2.0.11
-git push origin v2.0.1
+git push origin v2.0.11
 ```

+## 📥 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**.
+    * Click **Run anyway**.
+4. **Launch:** Once installed, you can launch the app directly from your Desktop or the Start menu.
+
+---
+
+### 🐧 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
+     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.
+
+4. **Troubleshooting:**
+   * **FUSE:** If the AppImage fails to launch on newer distributions, ensure `libfuse2` (or `fuse2` on Arch/Fedora) is installed.
+   * **Desktop Entry:** After installing via `.rpm`, `.deb`, or `.pkg.tar.zst`, the launcher should automatically appear in your App Library/Grid.
+   * Missing libxcrypt.so.1: Install `libxcrypt-compat` using your package manager
+
+---
+
+### 🍎 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: 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 STUN` or `Connected via UPnP`.
+
+## Dedicated Server
+
+> [!NOTE]
+> If you have already  `HytaleServer.jar` in `HytaleF2P/{release/pre-release}/package/game/latest/Server`, you can use it to host local dedicated server. 
+
+> [!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).
+
+> [!IMPORTANT]
+> See detailed information of setting up a server here: [SERVER.md](SERVER.md)

-# Hytale F2P Server Setup Guide
+# Hytale F2P Server Guide
 
-## Server File Setup
+Play with friends online! This guide covers both easy in-game hosting and advanced dedicated server setup.
 
-**Download server file:**
+DOWNLOAD SERVER FILES HERE: https://discord.gg/MEyWUxt77m
-```
-http://3.10.208.30:3002/server
-```
-
-**Replace the file here:**  
-`<your_path>\HytaleF2P\release\package\game\latest\Server`
-
-If you don't have any custom installation path:
-
-1. Press **WIN + R**  
-2. Type: `%localappdata%\HytaleF2P\release\package\game\latest\Server`  
-3. Press **Enter**
-
-You will be redirected to the correct folder automatically.
-
-## Network Setup - Radmin VPN Required
-
-**Important:** The server only supports third-party software for LAN-style connections. You must use **Radmin VPN** to connect players together.
-
-1. **Download and install [Radmin VPN](https://www.radmin-vpn.com/)**
-2. **Create or join a network** in Radmin VPN
-3. **All players must be connected** to the same Radmin network
-4. **Use the Radmin VPN IP address** to connect to the server
-
-This creates a virtual LAN environment that allows the Hytale server to work properly with multiple players.
-
-## RAM Allocation Guide (Windows)
-
-When you start a Hytale server using `start-server.bat`, Java will use very little memory by default.  
-This can cause slow startup, crashes, or the server not launching at all.
-
-**You should always allocate RAM in your launch command.**
-
-Edit your `start-server.bat` file and use the version that matches your PC:

-### PC with 4 GB RAM
+## Part 1: Playing with Friends (Online Play)
-*Best for small servers / testing*
+
+The easiest way to play with friends - no manual server setup required!
+
+### How It Works
+
+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
+
+For Online Play to work, you need:
+
+- **UPnP enabled** on your router (most routers have this on by default)
+- **Public IP address** from your ISP (not behind CGNAT)
+
+### Common Issues
+
+#### "NAT Type: Carrier-Grade NAT (CGNAT)" Warning
+
+If you see this message:
+```
+Connected via UPnP
+NAT Type: Carrier-Grade NAT (CGNAT)
+Warning: Your network configuration may prevent other players from connecting.
+```
+
+**What this means:** Your ISP doesn't give you a public IP address. Multiple customers share one public IP, which blocks incoming connections.
+
+**Solutions:**
+
+1. **Contact your ISP** - Request a public/static IP address (may cost extra)
+2. **Use a VPN with port forwarding** - Services like Mullvad, PIA, or AirVPN offer this
+3. **Use Radmin VPN or Playit.gg** - Create a virtual LAN with friends (see below)
+4. **Have a friend with public IP host instead**
+
+#### "UPnP Failed" or "Port Mapping Failed"
+
+**Check your router:**
+1. Log into router admin panel (usually `192.168.1.1` or `192.168.0.1`)
+2. Find UPnP settings (often under "Advanced" or "NAT")
+3. Enable UPnP if disabled
+4. Restart your router
+
+**If UPnP isn't available:**
+- Manually forward **port 5520 UDP** to your computer's local IP
+- See "Port Forwarding" section below
+
+#### "Strict NAT" or "Symmetric NAT"
+
+Some routers have restrictive NAT that blocks peer connections.
+
+**Try:**
+1. Enable "NAT Passthrough" or "NAT Filtering: Open" in router settings
+2. Put your device in router's DMZ (temporary test only)
+3. Use Radmin VPN as workaround
+
+### Workarounds for NAT/CGNAT Issues
+
+#### Option 1: 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)  
+2. **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`
+4. **Share the address** - Friends connect directly using this address
+
+Works with both Online Play and dedicated servers. No software needed for players joining.
+
+#### Option 2: Radmin VPN
+
+Creates a virtual LAN - all players need to install it:
+
+1. **Download [Radmin VPN](https://www.radmin-vpn.com/)** - All players install it
+2. **Create a network** - One person creates, others join with network name/password
+3. **Host via Online Play** - Use your Radmin VPN IP instead
+4. **Friends connect** - They'll see you on the virtual LAN
+
+Both options bypass all NAT/CGNAT issues. But for **Windows machines only!**
+
+#### Option 3: Tailscale
+It creates mesh VPN service that streamlines connecting devices and services securely across different networks. And **works crossplatform!!**
+
+1. All member's are required to download [Tailscale](https://tailscale.com/download) on your device.

+2. Create a **common tailscale** account which will shared among your friends to log in.
+3. Ask your **host to login in to thier tailscale client first**, then the other members.
+##### Host
+  1. Open your singleplayer world
+  2. Go to Online Play settings
+  3. Re-save your settings to generate a new share code
+##### Friends
+  1. Ensure Tailscale is connected
+2. Use the new share code to connect
+[To test your connection, ping the host's ipv4 mentioned in tailwind]

+## Part 2: Dedicated Server (Advanced)
+
+For 24/7 servers, custom configurations, or hosting on a VPS/dedicated machine.
+
+### Quick Start
+
+#### Step 1: Get the Server JAR
+
+The server scripts will automatically download the pre-patched server JAR if it's not present.
+
+**Option A:** Let the scripts download automatically (requires `HYTALE_SERVER_URL` to be configured)
+
+**Option B:** Manually place `HytaleServer.jar` (pre-patched for F2P) in the Server directory:
+
+- **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: 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.
+
+---
+
+## Network Setup (Dedicated Server)
+
+### Local Network (LAN)
+
+If all players are on the same network:
+1. Find your local IP: `ipconfig` (Windows) or `ifconfig` (Mac/Linux)
+2. Share this IP with players on your network
+3. Default port is `5520`
+
+### Port Forwarding (Internet Play)
+
+To allow direct internet connections:
+
+1. Forward **port 5520 (UDP)** in your router
+2. Find your public IP at [whatismyip.com](https://whatismyip.com)
+3. Share your public IP with players
+
+**Windows Firewall:**
+```powershell
+# Run as Administrator
+netsh advfirewall firewall add rule name="Hytale Server" dir=in action=allow protocol=UDP localport=5520
+```
+
+---
+
+## Configuration
+
+### Environment Variables
+
+Set these before running to customize your server:
+
+| Variable | Default | Description |
+|----------|---------|-------------|
+| `HYTALE_SERVER_URL` | (placeholder) | URL to download pre-patched server JAR |
+| `HYTALE_AUTH_DOMAIN` | `auth.sanasol.ws` | Auth server domain (4-16 chars) |
+| `HYTALE_BIND` | `0.0.0.0:5520` | Server IP and port |
+| `HYTALE_AUTH_MODE` | `authenticated` | Auth mode (see below) |
+| `HYTALE_SERVER_NAME` | `My Hytale Server` | Server display name |
+| `HYTALE_GAME_PATH` | (auto-detected) | Override game location |
+| `JVM_XMS` | `2G` | Minimum Java memory |
+| `JVM_XMX` | `4G` | Maximum Java memory |
+
+**Example (Windows):**
+```batch
+set HYTALE_SERVER_NAME=My Awesome Server
+set JVM_XMX=8G
+run_server.bat
+```
+
+**Example (Linux/macOS):**
+```bash
+HYTALE_SERVER_NAME="My Awesome Server" JVM_XMX=8G ./run_server.sh
+```
+
+### Authentication Modes
+
+| Mode | Description | Use Case |
+|------|-------------|----------|
+| `authenticated` | Players log in via F2P Launcher | Public servers |
+| `unauthenticated` | No login required | LAN parties, testing |
+| `singleplayer` | Local play only | Solo testing |
+
+---
+
+## RAM Allocation Guide
+
+Adjust memory based on your system:
+
+| System RAM | Players | JVM_XMS | JVM_XMX |
+|------------|---------|---------|---------|
+| 4 GB | 1-3 | `512M` | `2G` |
+| 8 GB | 3-8 | `1G` | `4G` |
+| 16 GB | 8-15 | `2G` | `8G` |
+| 32 GB | 15+ | `4G` | `12G` |
+
+**Example for large server:**
+```bash
+JVM_XMS=4G JVM_XMX=12G ./run_server.sh
+```
+
+**Tips:**
+- `-Xms` = minimum RAM (allocated at startup)
+- `-Xmx` = maximum RAM (upper limit)
+- Never allocate all your system RAM - leave room for OS
+- Start conservative and increase if needed
+
+---
+
+## Server Commands
+
+Once running, use these commands in the console:
+
+| Command | Description |
+|---------|-------------|
+| `help` | Show all commands |
+| `stop` | Stop server gracefully |
+| `save` | Force world save |
+| `list` | List online players |
+| `op <player>` | Give operator status |
+| `deop <player>` | Remove operator status |
+| `kick <player>` | Kick a player |
+| `ban <player>` | Ban a player |
+| `unban <player>` | Unban a player |

-### PC with 16 GB RAM
+## Troubleshooting
-*Perfect for large or modded servers*
+
+### "Java not found" or "Java version too old"
+
+**Java 21 is REQUIRED** (the server uses class file version 65.0).
+
+**Install Java 21:**
+- **Windows:** `winget install EclipseAdoptium.Temurin.21.JDK`
+- **macOS:** `brew install openjdk@21`
+- **Ubuntu:** `sudo apt install openjdk-21-jdk`
+- **Fedora:** `sudo dnf install java-21-openjdk`
+- **Arch:** `sudo pacman -S jdk21-openjdk`
+- **Download:** [adoptium.net/temurin/releases/?version=21](https://adoptium.net/temurin/releases/?version=21)
+
+**macOS: Set Java 21 as default:**
+```bash
+export JAVA_HOME=$(/usr/libexec/java_home -v 21)
+export PATH="$JAVA_HOME/bin:$PATH"
+```
+Add these lines to `~/.zshrc` or `~/.bash_profile` to make permanent.
+
+### "Game directory not found"
+
+- Download game via F2P Launcher first
+- Or set `HYTALE_GAME_PATH` environment variable
+- Check custom install path in launcher settings
+
+### "Assets.zip not found"
+
+Game files incomplete. Re-download via the launcher.
+
+### "Port already in use"
 
 ```bash
-java -Xms2G -Xmx8G -jar HytaleServer.jar --assets ..\Assets.zip
+./run_server.sh --bind 0.0.0.0:5521
 ```
 
-- Uses up to **8 GB**
+### "Out of memory"
-- Ideal for heavy worlds and plugins
+
+Increase JVM_XMX:
+```bash
+JVM_XMX=6G ./run_server.sh
+```
+
+### Players can't connect
+
+1. Server shows "Server Ready"?
+2. Using F2P Launcher (not official)?
+3. Port 5520 open in firewall?
+4. Port forwarding configured (for internet)?
+5. Try `--auth-mode unauthenticated` for testing
+
+### "Authentication failed"
+
+- Ensure players use F2P Launcher
+- Auth server may be temporarily down
+- Test with `--auth-mode unauthenticated`
 
 ---
 
-## Tips
+## Docker Deployment (Advanced)
 
-- `-Xms` = minimum RAM allocation
+For production servers, use Docker:
-- `-Xmx` = maximum RAM allocation  
-- **Never allocate all your system RAM** — Windows still needs memory to run
-- **Test your configuration** with a small world first
-- **Monitor server performance** and adjust RAM as needed
 
+```bash
+docker run -d \
+  --name hytale-server \
+  -p 5520:5520/udp \
+  -v ./data:/data \
+  -e HYTALE_AUTH_DOMAIN=auth.sanasol.ws \
+  -e HYTALE_SERVER_NAME="My Server" \
+  -e JVM_XMX=8G \
+  ghcr.io/hybrowse/hytale-server-docker:latest
+```
 
+See [Docker documentation](https://github.com/Hybrowse/hytale-server-docker) for details.

+# 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
+                ↓
+User can install on next restart
+```
+
+## 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'

+  
+  if (fs.existsSync(cacheDir)) {
+    fs.rmSync(cacheDir, { recursive: true, force: true });
+    console.log('Update cache cleared');
+  }

+# Steam Deck / Ubuntu LTS Crash Investigation
+
+## Status: UNSOLVED
+
+**Last updated:** 2026-01-27
+
+No stable solution found. jemalloc helps occasionally but crashes still occur randomly.
+
+---
+
+## 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)
+
+**Critical Finding:** The UNPATCHED original binary works fine on Steam Deck. The crash is caused by ANY binary patching.
+
+---
+
+## What Was Tried (All Failed)
+
+### Memory Allocators
+| Approach | Result |
+|----------|--------|
+| `LD_PRELOAD=/usr/lib/libjemalloc.so.2` | Works randomly (3/10 times), not stable |
+| `MALLOC_CHECK_=0` | No effect |
+| `MALLOC_PERTURB_=255` | No effect |
+| `GLIBC_TUNABLES=glibc.malloc.tcache_count=0` | No effect |
+
+### Process/Scheduling
+| Approach | Result |
+|----------|--------|
+| `taskset -c 0` (single core) | Game too slow, stuck at connecting |
+| `taskset -c 0,1` or `0-3` | Still crashes |
+| `nice -n 19` | No effect |
+| `chrt --idle 0` | No effect |
+| `strace -f` | No effect |
+
+### Linker/Loading
+| Approach | Result |
+|----------|--------|
+| `LD_BIND_NOW=1` | No effect |
+| Wrapper script with LD_PRELOAD | No effect |
+| Shell spawn with inline LD_PRELOAD | No effect |
+
+### Patching Variations
+| Approach | Result |
+|----------|--------|
+| Null-padding after replacement | Crashes (made it worse) |
+| No null-padding (develop behavior) | Still crashes |
+| Minimal patches (3 instead of 6) | Still crashes |
+| Ultra-minimal (1 patch - domain only) | Still crashes |
+| Skip sentry patch | Still crashes |
+| Skip subdomain patches | Still crashes |
+
+**Key Finding:** Even patching just 1 string (main domain only) causes the crash.
+
+---
+
+## String Occurrences Found
+
+### Length-Prefixed Format
+Found by default patcher mode:
+
+| Offset | Content | Notes |
+|--------|---------|-------|
+| 0x1bc5d63 | `hytale.com` | **Surrounded by x86 code!** |
+
+### UTF-16LE Format (3 occurrences)
+| Offset | Content |
+|--------|---------|
+| 0x1bc5ad7 | `sentry.hytale.com/...` |
+| 0x1bc5b3f | `https://hytale.com/help...` |
+| 0x1bc5bc9 | `store.hytale.com/?...` |
+
+---
+
+## Binary Analysis
+
+When patching with length-prefixed mode:
+
+```
+< 01bc5d60: 5933 b80a 0000 0068 0079 0074 0061 006c  Y3.....h.y.t.a.l
+< 01bc5d70: 0065 002e 0063 006f 006d 8933 8807 0000  .e...c.o.m.3....

+> 01bc5d60: 5933 b80a 0000 0073 0061 006e 0061 0073  Y3.....s.a.n.a.s
+> 01bc5d70: 006f 006c 002e 0077 0073 8933 8807 0000  .o.l...w.s.3....
+```
+
+**Structure:**
+```
+5933 b8 | 0a000000 | h.y.t.a.l.e...c.o.m | 8933 8807 0000
+???????? | len=10   | string content      | mov [rbx],esi?
+```
+
+- `5933 b8` before string - could be code or metadata
+- `0a 00 00 00` - .NET length prefix (10 characters)
+- String content in UTF-16LE
+- `89 33` after - this is `mov [rbx], esi` in x86-64!
+
+**The string is embedded near executable code, not in a clean data section.**
+
+---
+
+## GDB Stack Trace
+
+```
+#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
+#7-#24  HytaleClient code (asset decompression)
+```
+
+Crash occurs in `libzstd.so` during `free()` after "Finished handling RequiredAssets".
+
+---
+
+## Hypotheses
+
+### 1. .NET AOT String Metadata (Most Likely)
+.NET AOT may have precomputed hashes, checksums, or relocation info for strings. Modifying string content breaks internal consistency, causing memory corruption when the runtime tries to use related data structures.
+
+### 2. Code/Data Interleaving
+The strings are embedded near x86 code (`89 33` = `mov [rbx], esi`). .NET AOT may use relative offsets that get invalidated when we modify nearby bytes.
+
+### 3. Binary Checksums
+The binary may have integrity checks for certain sections that we're invalidating by patching.
+
+### 4. Timing-Dependent Race Condition
+The fact that it works randomly (~30% of the time with jemalloc) suggests a race condition that's affected by:
+- Memory layout changes from patching
+- Allocator behavior differences
+- CPU scheduling
+
+---
+
+## Valgrind Results (Misleading)
+
+- Valgrind showed NO memory corruption errors
+- Game ran successfully under Valgrind (slower execution)
+- This suggested jemalloc would fix it, but it doesn't consistently work
+
+The slowdown from Valgrind likely masks the race condition timing.
+
+---
+
+## Current Launcher Implementation
+
+The launcher attempts:
+1. Auto-detect jemalloc at common paths
+2. Auto-install jemalloc via pkexec if not found
+3. Launch game with `LD_PRELOAD` via shell command
+
+But this doesn't provide stable results.
+
+---
+
+## Potential Alternative Approaches (Not Yet Tried)
+
+### 1. LD_PRELOAD Network Hooking
+Instead of patching the binary, hook `getaddrinfo()` / `connect()` to redirect network calls at runtime. No binary modification needed.
+
+### 2. Local Proxy + Certificate
+Run a local HTTPS proxy that intercepts hytale.com traffic and redirects to custom server. Requires installing a custom CA certificate.
+
+### 3. DNS + iptables Redirect
+Use local DNS to resolve hytale.com to localhost, then iptables to redirect to actual custom server. Requires root/sudo.
+
+### 4. Container with Older glibc
+Run the game in a container with glibc < 2.41 where the stricter validation doesn't exist.
+
+### 5. Different Patching Location
+Find strings in a pure data section rather than code-adjacent areas.
+
+---
+
+## Files Reference
+
+**Binary:** `HytaleClient` (ELF 64-bit, ~39.9 MB)
+
+**Branch:** `fix/steamdeck-jemalloc-crash`
+
+---
+
+## Install jemalloc (Partial Mitigation)
+
+jemalloc may help in some cases (~30% success rate):
+
+```bash
+# Steam Deck / Arch Linux
+sudo pacman -S jemalloc
+
+# Ubuntu / Debian
+sudo apt install libjemalloc2
+
+# Fedora / RHEL
+sudo dnf install jemalloc
+```
+
+The launcher automatically uses jemalloc if found. To disable:
+```bash
+HYTALE_NO_JEMALLOC=1 npm start
+```
+
+---
+
+## Conclusion
+
+**No stable solution found.** The binary patching approach may be fundamentally incompatible with glibc 2.41's stricter heap validation when modifying .NET AOT compiled binaries.
+
+Alternative approaches (network hooking, proxy, container) may be required for reliable Steam Deck / Ubuntu LTS support.

+The crash is caused by glibc 2.41's stricter heap validation. Using jemalloc as the memory allocator fixes the issue.
+
+### Install jemalloc
+
+```bash
+# Steam Deck / Arch Linux
+sudo pacman -S jemalloc
+
+# Ubuntu / Debian
+sudo apt install libjemalloc2
+
+# Fedora / RHEL
+sudo dnf install jemalloc
+```
+
+### Launcher Auto-Detection
+
+The launcher automatically uses jemalloc when installed. No manual configuration needed.
+
+To disable (for testing):
+```bash
+HYTALE_NO_JEMALLOC=1 npm start
+```
+
+### Manual Launch with jemalloc
+
+```bash
+cd ~/.hytalef2p/release/package/game/latest
+
+LD_PRELOAD=/usr/lib/libjemalloc.so.2 ./Client/HytaleClient --app-dir /home/deck/.hytalef2p/release/package/game/latest --java-exec /home/deck/.hytalef2p/release/package/jre/latest/bin/java --auth-mode authenticated --uuid YOUR_UUID --name Player --identity-token YOUR_TOKEN --session-token YOUR_TOKEN --user-dir /home/deck/.hytalesaves
+```
+
+---
+
+## Debug Commands (for troubleshooting)
+
+### Base Command
+```bash
+cd ~/.hytalef2p/release/package/game/latest
+```
+
+### GDB Stack Trace (for crash analysis)
+```bash
+gdb -ex "run --app-dir ..." ./Client/HytaleClient
+
+# After crash:
+bt
+bt full
+info registers
+quit
+```
+
+### Test glibc tunables (alternative fixes that didn't work reliably)
+
+**Disable tcache:**
+```bash
+GLIBC_TUNABLES=glibc.malloc.tcache_count=0 ./Client/HytaleClient ...
+```
+
+**Disable heap validation:**
+```bash
+MALLOC_CHECK_=0 ./Client/HytaleClient ...
+```
+
+### Binary Validation
+```bash
+file ~/.hytalef2p/release/package/game/latest/Client/HytaleClient
+ldd ~/.hytalef2p/release/package/game/latest/Client/HytaleClient
+```
+
+### Hex Dump Commands
+```bash
+# Search for hytale.com UTF-16LE
+xxd ~/.hytalef2p/release/package/game/latest/Client/HytaleClient.original | grep "6800 7900 7400 6100 6c00 6500 2e00 6300 6f00 6d00"
+```
+
+---
+
+## Test Different Patch Modes
+
+```bash
+# Restore original
+cp ~/.hytalef2p/release/package/game/latest/Client/HytaleClient.original ~/.hytalef2p/release/package/game/latest/Client/HytaleClient
+rm ~/.hytalef2p/release/package/game/latest/Client/HytaleClient.patched_custom
+
+# Test UTF-16LE mode
+HYTALE_PATCH_MODE=utf16le HYTALE_AUTH_DOMAIN=sanasol.ws npm start
+
+# Test length-prefixed mode (default)
+HYTALE_AUTH_DOMAIN=sanasol.ws npm start

+# 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
