@alldoami Would you be able to give me a pointer for fixing the docs failure?

[alldoami]

@berosen if you run make docs it should fix the errors! You shouldn't be manually editing the docs.

Thanks @alldoami! It seems like tfplugindocs generates docs differently depending on the directory it's being run from. I believe it should be good to go now.
