Hi all, I've managed to fix most of the sphinx errors our docs build produces. I still get the a few warnings, but I think we can safely ignore most of them. There are still a few errors that touch parts of the docs I didn't write, specifically: yt-doc/source/advanced/creating_frontend.rst:: WARNING: document isn't included in any toctree yt-doc/source/advanced/reason_architecture.rst:: WARNING: document isn't included in any toctree yt-doc/source/visualizing/simulated_observations.rst:: WARNING: document isn't included in any toctree yt-doc/source/workshop.rst:: WARNING: document isn't included in any toctree The errors imply that these four files aren't accessible by navigating through the docs. Does anyone know how should these sections be integrated into the rest of the docs? I also get several errors complaining about missing images from the cookbook. Are the images not included in the repository for a reason? Is there a helper script somewhere to generate the images? If so, I'll look into integrating it into the build process. -Nathan
