+
+If you find an issue, submitting a pull request is always better than a bug report! Please fork and submit your code fixes.
+
+If you want to build some new features, we have a [roadmap.md](docs/roadmap.md) of features we want. You can add features you want there, or just code the feature and send a pull request.
