+# Contributing Guide
+
+First and foremost, thank you for contributing to this project led by the
+[CNCF Environmental Sustainability TAG](https://github.com/cncf/tag-env-sustainability)!
+We really appreciate your time and willingness to contribute. The [Green Reviews
+Working Group](https://github.com/cncf/tag-env-sustainability/tree/main/working-groups/green-reviews)
+is an entirely volunteer-led open-source project where we innovate
+in the open in the hopes of making this architectural reference available to
+everyone who operates in a cloud-native environment.
+
+Read on to learn more about the project and how to contribute. As always, please
+don't hesitate to ask if anything is unclear. We value questions, guidance, and
+suggestions - they help us build the right thing.
+
+### Finding Work
+
+Here are some suggestions for how to find work to contribute to the project.
+
+First, make sure you're up to speed with the project by looking through the resources in the [Getting Started](./README.md#getting-started) guide.
+
+Then, familiarise yourself with the current work and priorities, or find someone who would be willing to pair with you:
+- Join the twice monthly [WG meetings](https://github.com/cncf/tag-env-sustainability/tree/main/working-groups/green-reviews#meetings-and-contact).
+- [async] Leave a comment in any of the [issues](https://github.com/orgs/cncf/projects/10/views/12).
+- [async] Contribute to discussions in the CNCF Slack channel [#wg-green-reviews](https://cloud-native.slack.com/archives/C060EDHN431).
+
+When you feel ready to contribute:
+- Check the Backlog in the [issue board](https://github.com/orgs/cncf/projects/10/views/12). More pressing issues are labeled with `good first issue` or `help wanted`.
+- If you would like to make a feature request or raise a bug, feel free to [open an issue](https://github.com/cncf-tags/green-reviews-tooling/issues/new).
+- _If all else fails_, you could reach out to the [Green Review WG leads](https://github.com/cncf/tag-env-sustainability/tree/main/working-groups/green-reviews#chairs) directly with any queries. However, the public communication channels listed above are preferred so that we can load-balance the work.
+
+We encourage all communication to remain public by going through the communications channels listed above so that everyone can stay informed!
+
+### Opening a Pull Request
+
+Recommendations for a faster Pull Request review:
+- Please ensure that your commits are **signed** and **verified**.
+  - **Signed**: Include a `Signed-off-by: Author Name <[email protected]>` in all commits by doing `git rebase HEAD~2 --signoff` (replace `~2` with the number of commits to sign) and then `git push -f`. More info [here](https://github.com/cncf-tags/green-reviews-tooling/pull/53/checks?check_run_id=21563565653).
+  - **Verified**: [Learn more about commit signature verification with GPG.](https://docs.github.com/en/authentication/managing-commit-signature-verification/about-commit-signature-verification#gpg-commit-signature-verification)
+- The Kubernetes Best Practices for faster Reviews is a great resource for PR best practices: https://git.k8s.io/community/contributors/guide/pull-requests.md#best-practices-for-faster-reviews
