Note that I have toggled on the functionality to build docs for every PR.
If you click on "Details" after the docs/readthedocs.org:ufs-weather-model check at the bottom of the PR, you will either see the PR docs, the build progress (if it hasn't completed), or the traceback (if it fails). I believe that after 90 days, the build is deleted, so the docs are not stored indefinitely, but this will ensure that there are no obvious issues with the PR docs.

It is possible to turn on a "warn as error" functionality in the docs that will fail the build check when warnings appear (rather than just failing for errors). Let me know if you'd like me to turn on this functionality. It has the benefit of catching small issues as they occur (such as changes to URLs in the docs), which is helpful for maintenance. However, developers may not like having to fix issues like this that are outside their PR scope, even if they are usually small/simple fixes. That said, I'm happy to work with them to put the fixes into their PR or a subsequent PR if such issues occur.
