+
+##### IW4x | IW4-SP | IW5-Mod | IW6-Mod | S1-Mod
+
+---
+
+#### Installation
+
+1. Download the [latest alterware-launcher.exe](https://github.com/mxve/alterware-launcher/releases/latest/download/alterware-launcher.exe)

 3. Run alterware-launcher.exe, after updating the game will launch automatically
 
 ---
 
-- Passing ```iw4-sp```, ```iw5-mod```, ```iw6-mod``` or ```s1-mod``` as the first argument will skip automatic game detection
-- Passing ```update``` will stop the launcher from launching the game
-- ```skip-launcher-update``` skips self-update
+#### Command line arguments
+
+- ```iw4-sp```, ```iw4x```, ```iw5-mod```, ```iw6-mod```, ```s1-mod```
+  - Skip automatic detection and launch the specified game
+    - This should always be the first argument if used
+- ```--update```, ```-u```
+  - Only update the game, don't launch it
+- ```--skip-launcher-update```
+  - Don't update the launcher
+- ```--bonus```
+  - Download bonus content
+- ```--force```, ```-f```
+  - Force file hash recheck
+- ```--path```, ```-p```
+  - Set the game path
+    - Do not include a trailing backslash in the path
+- ```--pass```
+  - Pass additional arguments to the game
+- ```--version```, ```-v```
+  - Print the launcher version
+
+Example: ```alterware-launcher.exe iw4x --bonus -u --path "C:\Games\IW4x" --pass "-console"```
+
+Some arguments can be set in alterware-launcher.json, args generally override the values of the config.

+
+#### Support
+
+Visit the [AlterWare Forum](https://forum.alterware.dev/) or [Discord](https://discord.gg/2ETE8engZM) for support.
+
+---
+
+#### Building from Source
+
+- [Install Rust](https://rustup.rs/)
+- Clone the repository
+- Run ```cargo build --release```
+- The executable will be located in ```target/release```
+
+---
 
 ### Note for server owners:
 When the launcher updates itself it needs to be restarted. It will return exit code 201 in this case.
