+# Contributing To ZMK
+
+Thanks for taking an interest in contributing to ZMK! After reading through the documentation, if
+you have any questions, please come join us on the
+[ZMK Discord Server][discord-invite].
+
+## Code of Conduct
+
+All community members are expected to abide by the [Code of Conduct][code-of-conduct].
+For any and all conduct inquiries or concerns, please contact conduct@zmkfirmware.dev.
+
+[code-of-conduct]: https://github.com/zmkfirmware/zmk/blob/main/CODE_OF_CONDUCT.md
+
+## How Can I Contribute
+
+There are many different ways that you can contribute to ZMK, several of which require no coding
+abilities. These include:
+
+- Chat Support
+- Issue Reporting/Commenting
+- Testing
+- Documentation
+- Code Contributions
+
+## Chat Support
+
+Providing user support on the [ZMK Discord Server][discord-invite] is a great way to help the
+project. In particular, answering questions in the [#help](https://discord.com/channels/719497620560543766/719909884769992755) channel is incredibly appreciated.
+
+## Issue Reporting/Commenting
+
+Often, you might encounter unexpected behavior when building, flashing, or running the ZMK
+firmware. Submitting or commenting on issues on GitHub is a great way to contribute to the
+ZMK project.
+
+### Before Submitting a Report
+
+- Review the [Frequently Asked Questions](https://zmkfirmware.dev/docs/faq).
+- Check the [Troubleshooting Guide](https://zmkfirmware.dev/docs/troubleshooting) for answers.
+- Search the [open issues](https://github.com/zmkfirmware/zmk/issues) for an existing report that
+  matches your problem.
+
+### Opening A Report
+
+To open a report:
+
+- Head to https://github.com/zmkfirmware/zmk/issues/new
+- Provide an accurate summary of the issue in the title.
+- Provide as much detail as you can about the issue including:
+  - What [board/shield](https://zmkfirmware.dev/docs/faq#what-is-a-board) you are using.
+  - A link to the user repository, if you used it to build your firmware.
+  - Exact steps to reproduce the problem.
+  - Any relevant screenshots or [logs](https://zmkfirmware.dev/docs/dev-guide-usb-logging)
+
+## Testing
+
+The `help wanted` label will be added to any [pull requests](https://github.com/zmkfirmware/zmk/pulls?q=is%3Aopen+is%3Apr+label%3A%22help+wanted%22)
+or [issues](https://github.com/zmkfirmware/zmk/issues?q=is%3Aopen+is%3Aissue+label%3A%22help+wanted%22)
+where user testing can assist the ZMK contributors to verify fixes, confirm
+bugs, etc.
+
+When providing testing feedback, please provide:
+
+- Exact steps used to test
+- Any hardware details relevant to testing
+- Pass/fail summary for testing.
+- Full details of any failures, including:
+  - Logs
+  - Screenshots
+
+## Documentation
+
+Quality documentation is a huge part of what makes a successful project. Contributions to add
+documentation to areas not currently covered are greatly appreciated.
+
+### Contributing
+
+- The documentation site can be found in the main ZMK repo, in the
+  [docs/](https://github.com/zmkfirmware/zmk/tree/main/docs) subdirectory.
+- The documentation is maintained using [Docusaurus V2](https://v2.docusaurus.io/docs/).
+- To get started, from the `docs/` directory, run `npm ci` and then `npm start`.
+- Enhancements should be submitted as pull requests to the `main` branch of ZMK.
+
+## Code Contributions
+
+### Development Setup
+
+To get your development environment setup going, start at the
+[basic setup](https://zmkfirmware.dev/docs/dev-setup) docs, and make sure you can build and flash
+your own locally built firmware.
+
+### Formatting
+
+ZMK uses `clang-format` to ensure consist formatting for our source code. Before submitting your
+changes, make sure you've manually run `clang-format`, or have your IDE configured to auto-format
+on save.
+
+### Commit Messages
+
+The ZMK project is working towards, but not yet enforcing, the use of
+[conventional commits](https://www.conventionalcommits.org/en/v1.0.0/) for commit messages.
+
+Further documentation and details will be provided here soon.
+
+### Pull Requests
+
+When opening a pull request with your changes, please:
+
+- Submit the PR to the `main` branch of the
+  [`zmkfirmware/zmk`](https://github.com/zmkfirmware/zmk) repository.
+- Use a descriptive title that summarizes the change.
+- In the description, include:
+  - References to any open issues fixed by the PR.
+  - Feature added by the PR
+  - Bugs fixed by the PR.
+  - Testing you've performed locally.
+  - Requested testing by reviewers or testers.
+  - Screenshots or logs that support understanding the change.
