+# PettingZoo docs
+
+This folder contains the documentation for [PettingZoo](https://github.com/Farama-Foundation/PettingZoo).
+
+## Instructions for editing content
+
+Our documentation is written in Markdown (more precisely, MyST - Markedly Structured Text) and built using [Sphinx](https://www.sphinx-doc.org/en/master/).
+All content present in the documentation website can be found in this directory except for the environments.
+
+### Editing an environment page
+
+Environemnts' documentation can be found at the top of the file python file where the environment is declared, for example, the documentation for the chess environment can be at [/pettingzoo/classic/chess/chess.py](https://github.com/Farama-Foundation/PettingZoo/blob/master/pettingzoo/classic/chess/chess.py)
+
+To generate the environments pages you need to execute the `_scripts/gen_envs_mds.py` script.
+
+## Build the Documentation
+
+Install the required packages and PettingZoo:
+
+```
+pip install -e .
+cd docs/
+pip install -r requirements.txt
+```
+
+To build the documentation once:
+
+```
+cd docs
+make dirhtml _build
+```
+
+To rebuild the documentation automatically every time a change is made:
+
+```
+cd docs
+sphinx-autobuild -b dirhtml . _build
+```
