+## Pull Request Submissions.
+
+All pull requests should be made to the development branch. Details should be available describing your fix. Before submitting a pull request, please confirm that merge issues are resolved.
+
+<a href="#asking-questions"></a>
+## Asking Questions
+
+We don't use GitHub as a support forum.
+For any usage questions that are not specific to the project itself,
+please ask on [Stack Overflow](http://stackoverflow.com/questions/tagged/cosmicmind) instead.
+By doing so, you'll be more likely to quickly solve your problem,
+and you'll allow anyone else with the same question to find the answer.
+This also allows maintainers to focus on improving the project for others.
+
+<a href="#reporting-security-issues"></a>
+## Reporting Security Issues
+
+CosmicMind takes security seriously.
+If you discover a security issue, please bring it to our attention right away!
+
+Please **DO NOT** file a public issue,
+instead send your report privately to <support@cosmicmind.com>.
+This will help ensure that any vulnerabilities that _are_ found
+can be [disclosed responsibly](http://en.wikipedia.org/wiki/Responsible_disclosure)
+to any affected parties.
+
+<a href="#reporting-other-issues"></a>
+## Reporting Other Issues
+
+A great way to contribute to the project
+is to send a detailed issue when you encounter an problem.
+We always appreciate a well-written, thorough bug report.
+
+Check that the project issues database
+doesn't already include that problem or suggestion before submitting an issue.
+If you find a match, add a quick "+1" or "I have this problem too."
+Doing this helps prioritize the most common problems and requests.
+
+When reporting issues, please include the following:
+
+* The version of Xcode you're using
+* The version of iOS you're targeting
+* The full output of any stack trace or compiler error
+* A code snippet that reproduces the described behavior, if applicable
+* Any other details that would be useful in understanding the problem
+
+This information will help us review and fix your issue faster.
