+# Contributing
+
+:wave: Hi there!
+
+We're thrilled that you'd like to contribute to this project. Your help is
+essential for keeping it great.
+
+## Submitting a pull request
+
+We use [pull requests](https://github.com/exiguus/fta-github-action/pulls) to
+contribute new features, fixes, or documentation.
+
+Here are a few things you can do that will increase the likelihood of your pull
+request being accepted:
+
+- Keep your change as focused as possible. If there are multiple changes you
+  would like to make that are not dependent upon each other, submit them as
+  separate pull requests.
+- Write [conventional commits](https://www.conventionalcommits.org/en/v1.0.0/).
+- Write
+  [descriptive commit messages](https://tbaggery.com/2008/04/19/a-note-about-git-commit-messages.html).
+
+Draft pull requests are also welcome to get feedback early on, or if there is
+something blocking you.
