mkdocs doesn't look in the root of the repo

When you choose Mkdocs as your Documentation Type, we will first look for a mkdocs.yml file in the root of your repository. If we don’t find one, we will generate one for you.

The above is not true. I had a project with mkdocs.yml in the root (along with relevant markdown files), and the build failed-- I was getting the same error referenced in #4231.

A link to your rtd project and build would be helpful here, anyway, I think your issue was because of the docs_dir was at the same level of the mkdocs.yml file instead of a child directory, and btw, I think you mention that moving all inside docs solved the issue. It does, but we are not longer reading your mkdocs.yml file, but generating one for you in the root of your project.

Ah, you are correct! Just tested this here: AumitLeon/module_starter_cli#35. I updated #4508 to include info on where .md files are sourced from specifically.
