git/.github/PULL_REQUEST_TEMPLATE.md

Thanks for taking the time to contribute to Git! Please be advised that the Git community does not use github.com for their contributions. Instead, we use a mailing list (git@vger.kernel.org) for code submissions, code reviews, and bug reports. Nevertheless, you can use GitGitGadget (https://gitgitgadget.github.io/) to conveniently send your Pull Requests commits to our mailing list.

For a single-commit pull request, please leave the pull request description empty: your commit message itself should describe your changes.

Please read the "guidelines for contributing" linked above!
