+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.
 
-- ✅ **Valid**: `2.0.1`, `2.0.11`, `2.1.0`, `3.0.0`
-- ❌ **Invalid**: `2.0.2b`, `2.0.2a`, `2.0.1-beta`, `v2.0.2b`
+### 🐧 Linux Installation
 
-**Format**: `MAJOR.MINOR.PATCH` (e.g., `2.0.11`)
+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
+     ```
 
-- **MAJOR**: Breaking changes
-- **MINOR**: New features (backward compatible)
-- **PATCH**: Bug fixes (backward compatible)
+> [!NOTE]
+> Make sure to adjust the filename correctly with the version and the architecture type. TIP: Use `cd` command to the package location.
 
-**Why?** The auto-update system requires semantic versioning for proper version comparison. Letter suffixes (like `2.0.2b`) are not supported and will cause update detection issues.
+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`.
+
+## 🖧 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. 
+
+> [!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). Linux ARM64 is supported for server only.
+
+> [!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.

+# 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` |
