 Platforms are contained in specific directories which start with `p_`. 
 Usually platforms contain no additional header files.
 
+## Portability

+The codebase should be as portable as possible.
+To achive this the following restrictions are in place:
+- Software rendering only
+- No fpu use in core code
+- Prefer 32 bit integers

 ## Vendoring
 
 All 3rd party libraries should be forked and included as a submodule.
