+Contributions are **welcome** and will be fully **credited**.
+
+We accept contributions via Pull Requests on [Github](https://github.com/andreskrey/readability.php/).
+
+
+## Pull Requests
+
+- **Document any change in behaviour** - Make sure the `README.md` and any other relevant documentation are kept up-to-date.
+
+- **Add tests!** - Your patch won't be accepted if it doesn't have tests.
+
+- **Create feature branches** - Don't ask us to pull from your master branch.
+
+- **One pull request per feature** - If you want to do more than one thing, send multiple pull requests.
+
+- **Send coherent history** - Make sure each individual commit in your pull request is meaningful. If you had to make multiple intermediate commits while developing, please [squash them](http://www.git-scm.com/book/en/v2/Git-Tools-Rewriting-History#Changing-Multiple-Commit-Messages) before submitting.
+
+- **Don't forget to add yourself to AUTHORS.md** - If you want to be credited, make sure you add your information (whatever you want to include) in `AUTHORS.md`.
