Can we make docre parse this (with the space) as well? It's nice to keep syntax highlighting here

 - For state management, we encourage the use of the `state` value that Reprocessing manages for the user.  To use this, decide on a datatype representing the state and return the initial value from `setup`.  This will be persisted behind the scenes and passed to every callback (such as `draw` and `mouseDown`).  Each callback should return the new value of the state (or the old value if it doesn't change).
 
 - There are no built-in variables like `width` and `mouseX`.  Instead, these are functions that are called, passing in an environment object that is always provided.

 Check out [font-generator](https://github.com/bsansouci/font-generator) for a tool that can take any truetype or opentype font and output font files that Reprocessing can use.
 
 The assets folder of this repo also has an [example](https://github.com/Schmavery/reprocessing/tree/master/assets/font) of a font that can be copied to your project and used.  In order to use a font once you have the files:
