  +### Finding things to work on
  +
  +Known bugs and feature requests are all in the [issue tracker](https://github.com/ggez/ggez/issues) so that's a good place to start looking for places to help. Bugs marked `*EASY*` are fairly self-contained and probably don't need lots and lots of research. Bugs marked `*LESS EASY*` will require a bit of finesse, or larger/broader changes to the library.
