// Here's some code that I have so far for raylib, not sure how to get all of it set up with github at the moment, 
// and variable names are bound to change, so I'm just leving it here for the moment

// here are instructions i used for setting up raylib on my mac, 
// you can just copy/paste this into a new project to try it out.
