+Development Guide
+-----------------
+This is a guide for developers who would like to contribute to this project.
+
+Git Workflow
+------------
+
+If you're interested in contributing to pgcli, first of all my heart felt
+thanks. Please `fork the project <https://github.com/amjith/pgcli>`_ in github.
+Then clone your fork into your computer (``git clone <url-for-your-fork>``).
+Make the necessary changes and create the commits in your local machine. Then
+push those changes to your fork. Then click on the pull request icon on github
+and create a new pull request. Add a description about the change and send it
+along. I promise to review you in a reasonable window of time and get back to
+you. 
+
+In order to keep your fork up to date with any changes from mainline, add a new
+git remote to your local copy called 'upstream' and point it to the main pgcli
+repo.
+
+.. :: 
+
+   $ git remote add upstream git@github.com:amjith/pgcli.git
+
+Once the 'upstream' end point is added you can then periodically do a ``git
+pull upstream master`` to update your local copy and then do a ``git push
+origin master`` to keep your own fork up to date. 
+
+Local Setup
+-----------
+
+The installation instructions in the README file are intended for users of
+pgcli. If you're developing pgcli, you'll need to install it in a slightly
+different way so you can see the effects of your changes right away without
+having to go through the install cycle everytime you change the code.
+
+It is highly recommended to use virtualenv for development. If you don't know
+what a virtualenv is, this `guide <http://docs.python-guide.org/en/latest/dev/virtualenvs/#virtual-environments>`_
+will help you get started.
+
+Create a virtualenv (let's call it pgcli-dev). Once the virtualenv is activated
+`cd` into the local clone of pgcli folder and install pgcli using pip as
+follows:
+
+.. ::
+
+    $ pip install --editable .
+
+    or
+
+    $ pip install -e .
+
+This will install the necessary dependencies as well as install pgcli from the
+working folder into the virtualenv. By installing it using `pip install -e`
+we've linked the pgcli installation with the working copy. So any changes made
+to the code is immediately available in the installed version of pgcli. This
+makes it easy to change something in the code, launch pgcli and check the
+effects of your change.
