+How to Contribute
+=================
+
+There are no plans to develop Cerberus further than the current feature set.
+Bug fixes and documentation improvements are welcome and will be published with
+yearly service releases.
+
+
+Making Changes
+--------------
+* Fork_ the repository_ on GitHub.
+* Create a new topic branch from the ``1.3.x`` branch.
+* Make commits of logical units (if needed rebase your feature branch before
+ submitting it).
+* Make sure your commit messages are in the `proper format`_.
+* If your commit fixes an open issue, reference it in the commit message.
+* Make sure you have added the necessary tests for your changes.
+* Run all the tests to assure nothing else was accidentally broken.
+* Install and enable pre-commit_ (``pip install pre-commit``, then ``pre-commit
+ install``) to ensure styleguides and codechecks are followed.
+* Don't forget to add yourself to the ``AUTHORS.rst`` document.
+
+These guidelines also apply when helping with documentation (actually, for
+typos and minor additions you might choose to `fork and edit`_).
+
+
+Submitting Changes
+------------------
+* Push your changes to the topic branch in your fork of the repository.
+* Submit a `Pull Request`_.
+* Wait for maintainer feedback. Please be patient.

 Development Version
 -------------------
 
-Cerberus is actively developed in a `GitHub Repository`_ where the code. If you
-want to work with the development version, there are two ways: You can either
-let ``pip`` pull in the development version, or you can tell it to operate on a
-``git`` checkout. Either way, virtualenv is recommended.
-
-Get the git checkout in a new virtualenv and run in development mode.
+Obtain the source (either as source distribution from the PyPI, with ``git`` or
+other means that the Github platform provides) and use the following command
+in the source's root directory for an editable installation. Subsequent changes
+to the source code will affect its following execution without re-installation.
 
 .. code-block:: console
 
- $ git clone [email protected]:pyeve/cerberus.git
- Initialized empty Git repository in ~/dev/cerberus.git/
- $ cd cerberus
- $ virtualenv venv --distribute
- New python executable in venv/bin/python
- Installing distribute............done.
- $ . venv/bin/activate
  $ pip install -e .
- ...
- Finished processing dependencies for Cerberus
-
-This will pull in the dependencies and activate the git head as the current
-version inside the virtualenv. Then all you have to do is run ``git pull
-origin`` to update to the latest version.
-
-To just get the development version without git, do this instead:
-
-.. code-block:: console
-
- $ mkdir cerberus
- $ cd cerberus
- $ virtualenv venv --distribute
- $ . venv/bin/activate
- New python executable in venv/bin/python
- Installing distribute............done.
