+
+## Reporting Bugs/Feature Requests
+
+We welcome you to use the GitHub issue tracker to report bugs or suggest features.
+
+When filing an issue, please check [existing open][issues], or [recently closed][closed-issues], issues to make sure
+ somebody else hasn't already reported the issue.
+Please try to include as much information as you can. Details like these are incredibly useful:
+
+* A reproducible test case or series of steps
+* The version of our code being used
+* Any modifications you've made relevant to the bug
+* Anything unusual about your environment or deployment
+
+## Contributing via Pull Requests
+
+To send us a pull request, please:
+
+1. Fork the repository.
+2. Modify the source; please focus on the specific change you are contributing.
+  If you also reformat all the code, it will be hard for us to focus on your change.
+3. Ensure local tests pass. (`colcon test` and `pre-commit run` (requires you to install pre-commit by `pip3 install pre-commit`)
+4. Commit to your fork using clear commit messages.
+5. Send a pull request, answering any default questions in the pull request interface.
+6. Pay attention to any automated CI failures reported in the pull request, and stay involved in the conversation.

+[creating a pull request](https://help.github.com/articles/creating-a-pull-request/).
+
+## Finding contributions to work on
+
+Looking at the existing issues is a great way to find something to contribute on.
+As this project, by default, uses the default GitHub issue labels
+  (enhancement/bug/duplicate/help wanted/invalid/question/wontfix), looking at any ['help wanted'][help-wanted] issues
+  is a great place to start.
