+# Guidance on how to contribute
+
+> By submitting a pull request or filing a bug, issue, or feature request,
+> you are agreeing to comply with this waiver of copyright interest.
+> Details can be found in our [LICENSE](LICENSE).
+
+
+There are two primary ways to help:
+- Using the issue tracker, and
+- Changing the code-base.
+
+
+## Using the issue tracker
+
+Use the issue tracker to suggest feature requests, report bugs, and ask questions.
+This is also a great way to connect with the developers of the project as well
+as others who are interested in this solution.
+
+Use the issue tracker to find ways to contribute. Find a bug or a feature, mention in
+the issue that you will take on that effort, then follow the _Changing the code-base_
+guidance below.
+
+
+## Changing the code-base
+
+Generally speaking, you should fork this repository, make changes in your
+own fork, and then submit a pull request. All new code should have associated
+unit tests that validate implemented features and the presence or lack of defects.
+Additionally, the code should follow any stylistic and architectural guidelines
+prescribed by the project. In the absence of such guidelines, mimic the styles
+and patterns in the existing code-base.
