+## Get Started!
+
+Ready to contribute? Here's how to set up `prometheus-es-adapter` for local development.
+
+1. Fork the `prometheus-es-adapter` repo on GitHub.
+2. Clone your fork locally::
+
+    $ git clone [email protected]:your_name_here/prometheus-es-adapter.git
+
+3. Create a branch for local development::
+
+    $ git checkout -b name-of-your-bugfix-or-feature
+
+   Now you can make your changes locally.
+
+4. When you're done making changes, check that your changes pass the tests::
+
+    $ make test
+
+6. Commit your changes and push your branch to GitHub::
+
+    $ git add .
+    $ git commit -m "Your detailed description of your changes."
+    $ git push origin name-of-your-bugfix-or-feature
+
+7. Submit a pull request through the GitHub website.
+
+Pull Request Guidelines
+-----------------------
+
+Before you submit a pull request, check that it meets these guidelines:
+
+1. The pull request should include tests.
+2. If the pull request adds functionality, the docs should be updated. Put
+   your new functionality into a function with a docstring, and add the
+   feature to the list in README.md.
