+# How To Contribute
+
+## Some Ways to Contribute
+- Getting started with [L3AF](https://wiki.lfnetworking.org/display/L3AF/Getting+Started+with+L3AF)
+- Report potential bugs
+- Suggest product enhancements
+- Increase our test coverage
+- Fix a bug
+- Implement a requested enhancement
+- Improve our guides and documentation
+- Contribute code
+
+### Report potential bugs
+
+First, **ensure the bug was not already reported** by searching on GitHub under
+[Issues](https://github.com/l3af-project/l3afd/issues).
+
+If you did not find a related bug, you can help us by
+[submitting a GitHub Issue](https://github.com/l3af-project/l3afd/issues/new).
+A good bug report provides a detailed description of the issue and step-by-step instructions
+for reliably reproducing the issue.
+
+We will aim to triage issues in weekly TSC meetings. In case we are unable to repro the issue,
+we will request more information from you. There will be a waiting period of 2 weeks
+for the requested information and if there is no response, the issue will be closed. If this happens,
+please reopen the issue if you do get a repro and provide the requested information.
+
+If you found a security issue, please do not open a GitHub Issue, and instead [email]([email protected]) it in detail.
+
+### Submitting a patch that fixes a bug
+
+Fork the repo and make your changes. Then open a new GitHub pull request with the patch.
+
+* Ensure the PR description clearly describes the problem and solution. Include the relevant issue number
+  if applicable.
+
+## Guidelines for pull Requests
+
+Great, you want to directly contribute to the l3af project and submit a pull request.
+It is recommended prior to working on a PR to submit an issue in github for the change you want
+to make describing the change and context around it. This gives the l3af maintainers a chance to review
+the issue and provide feedback and work with you on the change. If you have any questions, please
+feel free to reach out to the l3af team via [Slack](https://app.slack.com/client/T02GD9YQJUT/C02GRTC0SAD) or
+[mail]([email protected]) group. Below are some general guidelines to help ensure a successful PR approval.
+
+- Provide background why you are making the change and the issue it addresses
+- List what is changing and provide a high-level summary of the change
+- List any relevant dependencies linked to this change
+- Describe the tests that you ran to verify your changes and add/update test cases
+- Update relevant docs, especially if you've change API's
+- Ensure all GitHub CI/CD checks pass

+early feedback will help ensure your implementation work is accepted by the community.

+## Developer Certificate of Origin (DCO)

+The [Developer Certificate of Origin](https://developercertificate.org/) is a lightweight way for contributors
+to certify that they wrote or otherwise have the right to submit the code they are contributing to the project.
+This App enforces the Developer Certificate of Origin on Pull Requests. It requires all commit messages to contain
+the ```Signed-off-by``` line with an email address that matches the commit author.
