Have a look at https://scipy.github.io/devdocs/dev/contributor/rendering_documentation.html
For building all the documentation artifacts for a release, run:
make dist
This will build SciPy in-place (to ensure the version is correct), build html and pdf docs as well as create a zip archive of the html docs that can easily be redistributed.
source
is where most of the content lives.dev
contains the contributor and developer guides as well as the governance docs and the code of conduct.tutorial
contains all tutorial content.release
contains the release notes. Note that those normally should not be updated as part of a PR; we keep release notes for the upcoming releases on the wiki of the main SciPy repo.
