This repo contains the NEW website for Gym. This site is currently in Beta and we are in the process of adding/editing information.

The documentation uses Sphinx. However, the documentation is written in regular md, NOT rst.

If you are modifying a non-environment page or an atari environment page, please PR this repo. Otherwise, follow the steps below:

If you are editing an Atari environment, directly edit the md file in this repository.

Otherwise, fork Gym and edit the docstring in the environment's Python file. Then, pip install your Gym fork and run docs/scripts/gen_mds.py in this repo. This will automatically generate a md documentation file for the environment.

For Atari envs, add a md file into pages/environments/atari then complete the other steps.

Ensure the environment is in Gym (or your fork). Ensure that the environment's Python file has a properly formatted markdown docstring. Pip install Gym (or your fork) then run docs/scripts/gen_mds.py. This will automatically generate an md page for the environment. Then complete the other steps.

• Add the corresponding gif into the docs/source/_static/videos/{ENV_TYPE} folder, where ENV_TYPE is the category of your new environment (e.g. mujoco). Follow snake_case naming convention. Alternatively, run docs/scripts/gen_gifs.py.
• Edit docs/source/environments/{ENV_TYPE}/index.md, and add the name of the file corresponding to your new environment to the toctree.

Install the required packages and Gym (or your fork):

pip install -r requirements.txt
pip install gym

To build the documentation once:

cd docs
make dirhtml

To rebuild the documentation automatically everytime a change is made:

cd docs
sphinx-autobuild -b dirhtml ./source build/html
