Thank you for this heroic effort! I just have a few minor comments.

Many, many thanks! This looks like a massive improvement! I have added some comments to the code and have one general question about the documentation: Does it really make sense to have all the .rst files in the repository? Can't they just be generated on Read the Docs and locally when they are needed?

@jougs I have created an issue to separate building the models documentation #880. We will address it in a separate PR.

Some suggestions and a question on formulations of the text. Otherwise, I think I'm fine.
