 ### raylib philosophy
 
  - raylib is a tool to enjoy videogames programming, every single function in raylib should be a tutorial on itself.
  - raylib is SIMPLE and EASY-TO-USE, I tried to keep it compact with a small set of functions, if a function is too complex or is not clearly useful, better not to include it.
  - raylib is open source and free; educators and institutions can use this tool to TEACH videogames programming completely by free.
- - raylib is collaborative; contribution of tutorials / code-examples / bugs-solving / code-comments are highly appreciated.
+ - raylib is collaborative; contribution of tutorials / code examples / bug fixes / code comments are highly appreciated.
  - raylib's license (and its external libs respective licenses) allow using it for commercial products.
