 This document is intended to detail some of the inner workings of Ganga to both document what we have done as well as make it easier for new developers to get on-board quicker.
 
+Get started with development:
+-----------
+
+Working on the Codebase
+^^^^^^^^^^^^^^^
+To get started with contributing & making changes to the Ganga Codebase:
+
+1. Developers need to clone the repository with:
+
+   .. code-block:: bash
+
+      git clone https://github.com/ganga-devs/ganga.git
+
+2. They need to go into the root of the project with :
+
+   .. code-block:: bash
+
+      cd ganga
+
+3. Then, run the following command to install ganga from the repo as an editable python package with relevant runtime, coverage & test packages :
+
+   .. code-block:: bash
+
+      pip install -e .[dev]
+
+   Now all changes made to the Ganga codebase will be reflected real-time
+
+4. To test their changes, developers can either initiate the ganga shell with the ganga command or invoke it via a python script.
+
+Working on the Documentation
+^^^^^^^^^^^^^^^
+To get started with contributing & making changes to the Ganga Codebase:
+
+1. Developers need to install **Sphinx** Documentation generator. Installation instructions can be found on `their website <https://www.sphinx-doc.org/en/master/usage/installation.html>`_.
+
+   .. note::
+       Since documentation is generated using a **Makefile** in ``the ganga/doc/`` folder, users may also need to install ``make`` on their systems, i.e., a build tool that can run makefiles
+
+2. Developers need to clone the repository with:
+
+   .. code-block:: bash
+
+      git clone https://github.com/ganga-devs/ganga.git
+
+3. They need to go into the docs folder i.e. ``ganga/doc/`` of the project with :
+
+   .. code-block:: bash
+
+      cd ganga/doc
+
+
+4. Then, run the following command to generate documentation in the required format :
+
+   .. code-block:: bash
+
+      make <target>
+
+   .. note::
+
+       The supported list of targets are:
+
+       .. list-table::
+          :widths: 25 75
+          :header-rows: 1

+            - to make an epub.
+          * - ``latex``
+            - to make LaTeX files, you can set PAPER=a4 or PAPER=letter.
+          * - ``latexpdf``
+            - to make LaTeX files and run them through pdflatex.
+          * - ``latexpdfja``
+            - to make LaTeX files and run them through platex/dvipdfmx.
+          * - ``text``
+            - to make text files.
+          * - ``man``

+          * - ``apidoc``
+            - to create RST files from source code documentation.
+
+5. This would generate a ``_build/`` folder which would contain the relevant output files.
+
+6. Now, all changes made to the Ganga Documentation can be tested/previewed by re-running above command after making the change.
