+
+## Get started!
+
+Ready to contribute? Here's how to set up `cached-property` for local development.
+
+1. Fork the `cached-property` repo on GitHub.
+2. Clone your fork locally::
+
+    ```bash
+    $ git clone git@github.com:your_name_here/cached-property.git
+    ```
+
+3. Install your local copy into a virtualenv. Assuming you have virtualenvwrapper installed, this is how you set up your fork for local development:
+
+    ```bash
+    $ mkvirtualenv cached-property
+    $ cd cached-property/
+    $ python setup.py develop
+    ```
+
+4. Create a branch for local development:
+
+    ```bash
+    $ git checkout -b name-of-your-bugfix-or-feature
+    ```
+
+    Now you can make your changes locally.
+
+5. Clean up the formatting (must be running at least Python 3.6):
+
+    ```bash
+    $ pip install -U black
+    $ black .
+    ```
+
+6. When you're done making changes, check that your changes pass the tests, including testing other Python versions with tox:
+
+    ```bash
+    $ pytest tests/
+    $ tox
+    ```
+
+   To get tox, just pip install it into your virtualenv.
+
+7. Commit your changes and push your branch to GitHub::
+
+    ```bash
+    $ git add .
+    $ git commit -m "Your detailed description of your changes."
+    $ git push origin name-of-your-bugfix-or-feature
+    ```
+
+8. 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.rst.
+3. The pull request should work for Python 2.7, and 3.3, 3.4, 3.5, 3.6 and for PyPy. Check https://travis-ci.org/pydanny/cached-property/pull_requests and make sure that the tests pass for all supported Python versions.
+
+## Tips
+
+To run a subset of tests:
+
+```bash
+$ python -m unittest tests.test_cached-property
+```
