+You will have to compile Raylib, and then copy the archive file into igcp's `lib` directory:
+
+```
+git clone --depth 1 https://github.com/raysan5/raylib.git raylib
+cd raylib/src/
+make PLATFORM=PLATFORM_DESKTOP
+
+cp libraylib.a PATH/TO/igcp/lib/
 ```
 
 # Compilation & Usage
 
+Now you can compile igcp and use it:
+
 ```
