+Setting up your development environment
+========================================
+
+The AWX docs are developed using the Python toolchain. The content itself is authored in ReStructuredText (rst).
+
+Prerequisites
+---------------
+
+.. contents::
+    :local:
+
+
+Fork and clone the AWX repo
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If you have not done so already, you'll need to fork the AWX repo on GitHub. For more on how to do this, see `Fork a Repo <https://help.github.com/articles/fork-a-repo/>`_.
+
+
+Install python and setuptools
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Install the setuptools package on Linux using pip:
+
+
+1. If not already installed, `download the latest version of Python3 <https://www.geeksforgeeks.org/how-to-download-and-install-python-latest-version-on-linux/>`_ on your machine.
+
+2. Check if pip3 and python3 are correctly installed in your system using the following command:
+
+::
+
+	python3 --version
+	pip3 --version
+
+3. Upgrade pip3 to the latest version to prevent installation issues:
+
+::
+
+	pip3 install --upgrade pip
+
+4. Install Setuptools:
+
+::
+
+	pip3 install setuptools
+
+5. Verify whether the Setuptools has been properly installed: 
+
+::
+
+	import setuptools
+
+If no errors are returned, then the package was installed properly.
+
+6. Install the tox package so you can build the docs locally:
+
+::
+
+	pip3 install tox
+
+
+
+Run local build of the docs
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+To build the docs on your local machine, use the tox utility. In your forked branch of your AWX repo, run: 
+
+::
+
+	tox -e docs  
+
+
+Access the AWX user interface
+------------------------------
+
+To access an instance of the AWX interface, refer to `Build and run the development environment <https://github.com/ansible/awx/blob/devel/CONTRIBUTING.md#setting-up-your-development-environment>`_ for detail. Once you have your environment setup, you can access the AWX UI by logging into it at `https://localhost:8043 <https://localhost:8043>`_, and access the API directly at `https://localhost:8043/api/ <https://localhost:8043/api/>`_.
