 This is a static recompilation of **Condemned 2: Bloodshot (Xbox 360)** for Native PC built through RexGlue-SDK. 
 
 ## Installation
-* Using [extract-xiso](https://github.com/XboxDev/extract-xiso) or [xdvdfs](https://github.com/antangelo/xdvdfs), extract all game files from your legally owned copy of **Condemned 2: Bloodshot**. 
+* Run *"condemned2recomp.exe"*. On first launch it asks for the disc image (*.iso*) dumped from your legally owned copy of **Condemned 2: Bloodshot** and extracts the game files into the *"Assets"* folder for you (~7 GiB of free space needed).
+* **(Optional)** Configure your graphic settings by modifying *"condemned2recomp.toml"*.

 * Place extracted game files into the *"Assets"* folder.
-* **(Optional)** Configure your graphic settings by modifying *"condemned2recomp.toml"*.
-* Run *"condemned2recomp.exe"* to start **Condemned 2: Bloodshot**.
