+
+Get Started!
+------------
+
+Ready to contribute? Here's how to set up `s2watchdog` for local development.
+
+1. Fork the `s2watchdog` repo on GitHub.
+2. Clone your fork locally::
+
+    `$ git clone git@github.com:your_name_here/s2watchdog.git`
+
+3. Install your local copy into a virtualenv.
+
+    `$ cd s2watchdog/`
+    `$ make devenv`
+
+4. Create a branch for local development::
+
+    `$ git checkout -b name-of-your-bugfix-or-feature`
+
+   Now you can make your changes locally.
+
+5. When you're done making changes, check that your changes passes the linters and the
+   tests, including testing other Python versions with tox::
+
+    ```
+    $ make lint
+    $ make coverage
+    $ make tox
+    ```
+
+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 and CHANGES.md
+
+Tips
+----
+
+To run a quick set of tests without coverage report
+
+    $ make test
+
+Deploying
+---------
+
+A reminder for the maintainers on how to deploy.
+Bump the version in `s2watchdog/__init__.py` and
+make sure all your changes are committed (including an entry in CHANGES.md).
+
+	$ git tag <new version>
+	$ git push

-The beerware license is very open, close to public domain, but insists on

-Instead assume that someone writing Open Source Software in the domain you’re

-So, just keep the name and contact details intact and if you ever meet the
