Just file an issue here with a description of your problem. If you are reporting a bug, tell us as many information as possible (e. g. on which platform you are running the software, the steps to reproduce, screenshots...).
Just send us a Pull Request. We are not really enforcing any rules, code coverage and stuff like that, but please, be reasonable and make sure that the build with your changes is passing on Travis CI.
