-So you want to hack on Knative Serving? Yay! Please refer to Knative
-Serving's overall [contribution guidelines](community/CONTRIBUTING.md)
-to find out how you can help.
+**First off, thanks for taking the time to contribute!**
+
+The following is a set of guidelines for contributing to Knative documentation.
+These are just guidelines, not rules. Use your best judgment, and feel free to
+propose changes to this document in a pull request.
+
+## Before you get started
+
+### Code of Conduct
+
+Knative follows the [Knative Code of Conduct](code-of-conduct.md). By
+participating, you are expected to uphold this code. Please report unacceptable
+behavior to knative-code-of-conduct@googlegroups.com.
+
+## Contributing to Documentation
+
+### Reporting Documentation Issues
+
+Knative uses github issues to track documentation issues and requests. If you
+see a documentation issue, submit an issue using the following steps:
+
+1. Check the [Knative docs issues list](https://github.com/knative/docs/issues)
+   as you might find out the issue is a duplicate.
+2. Use the [included template for every new issue](https://github.com/knative/docs/issues/new).
+   When you create a bug report, include as many details as possible and include
+   suggested fixes to the issue.
+
+Note that code issues should be filed against the individual Knative repositories,
+while documentation issues should go in the `docs` repository.
+
+### Submitting Documentation Pull Requests
+
+If you're fixing an issue in the existing documentation, you should submit a
+PR against the master branch.
