-- `make html` - Launch a one off build of HTML output.
-- `make clean` - Clean all the build directories. This can be useful as Sphinx tries to do incremental builds, and sometimes it will end up out of sync.

 - `conf.pd` - This is the Sphinx configuration file.
-- `environment.yml` - The conda environment needed to build the website.
+- `pixi.toml` - The conda environment needed to build the website.
 - `requirements.txt` - A pip installable environment to build the website. This is mainly used by Netlify to create previews of Pull Requests. It is generated with `pip list --format=freeze > requirements.txt`
 - `posts.md` - A stub page that is replaced when blog posts are generated.
 - `_build/` - Automatically generated output from Sphinx.
