In order to contribute new or updated code, you must first create a GitHub account and fork the original repository to your own account. You can make changes, save them in your repository, then [make a pull request](https://docs.github.com/en/github/collaborating-with-pull-requests/proposing-changes-to-your-work-with-pull-requests/creating-a-pull-request-from-a-fork) against this repository. The pull request will appear [in the repository](https://github.com/raspberrypi/pico-sdk/pulls) where it can be assessed by the maintainers, and if appropriate, merged with the official repository.
-**NOTE:** Development takes place on the `develop` branch in this repository. Please open your https://github.com/raspberrypi/pico-sdk/pulls[pull request] (PR) against the [`develop`](https://github.com/raspberrypi/pico-sdk/tree/develop) branch, pull requests against the `master` branch will automatically CI fail checks and will not be accepted. You will be asked to rebase your PR against `develop` and if you do not do so, your PR will be closed.

While we are happy to take contributions, big or small, changes in the SDK may have knock-on effects in other places so it is possible that apparently benign pull requests that make seemingly small changes could be refused.
