Build the Documentation

The following sections describe how to set up and build the NeMo RL documentation.

Switch to the documentation source folder and generate HTML output.

cd docs/
uv run --group docs sphinx-build . _build/html

• The resulting HTML files are generated in a _build/html folder that is created under the project docs/ folder.
• The generated python API docs are placed in apidocs under the docs/ folder.

Checking for Broken Links

To check for broken http links in the docs, run this command:

cd docs/
uv run --group docs sphinx-build --builder linkcheck . _build/linkcheck

It will output a JSON file at _build/linkcheck/output.json with links it found while building the docs. Records will have a status of broken if the link is not reachable. The docs/conf.py file is configured to ignore github links because the CI test will often experience rate limit errors. Comment out the linkcheck_ignore variable there to check all the links.

Live Building

When writing documentation, it can be helpful to serve the documentation and have it update live while you edit.

To do so, run:

cd docs/
uv run --group docs sphinx-autobuild . _build/html --port 12345 --host 0.0.0.0

Open a web browser and go to http://${HOST_WHERE_SPHINX_COMMAND_RUN}:12345 to view the output.
