+How to Contribute
+=================
+
+Pull Requests
+-------------
+
+1. Pull requests are welcome. If you would like to add a large feature
+or make a significant change, make sure to open an issue to discuss with
+people first.
+2. Follow PEP8.
+3. Make sure to pass the unit tests. Write unit tests for new modules if
+needed.
+
+Issues
+------
+
+1. Only bugs and feature requests are accepted here.
+2. We'll only work on important features. If the feature you're asking only
+benefits a few people, you'd better implement the feature yourself and send us
+a pull request, or ask some of your friends to do so.
+3. We don't answer questions of any other types here. Since very few people
+are watching the issue tracker here, you'll probably get no help from here.
+Read [Troubleshooting] and get help from forums or [mailing lists].
+4. Issues in languages other than English will be Google translated into English
+later.
