Read the Docs builds are throwing the following error: > Config validation error in `build.os`. Value `build` not found. This commit attempts to address all of the anticipated failures.
This is the full text of the Sphinx warning: ``` WARNING: Invalid configuration value found: 'language = None'. Update your configuration to a valid language code. Falling back to 'en' (English). ```
The full text of the Sphinx info message is:
```
Converting `source_suffix = '.rst'` to `source_suffix = {'.rst': 'restructuredtext'}`.
```
Two warnings were thrown for the same underlying issue: ``` WARNING: py:exc reference target not found: seekpath.SupercellWarning [ref.exc] ```

There was a problem hiding this comment.
Thanks a lot @kurtmckee !
I'll merge this one first, as you also addressed the warnings that I also found locally.
I'll then update my own fix in #114 to restructure the dependencies.
