I moved documentation files in a recent PR, so you'll need to update your branch. I recommend asking your agent to do it (and you can point it to the PR description for context).

@pimlock Thank you for catching! Removed "Documentation"

Now the "Home" is indented a bit too much. It may need a custom CSS?

@pimlock We can remove it if you think this is unnecessary. We added it before per Kirit's ask cause it was not obvious how to go back to the landing page. We had Table of Content at the top of the TOC before, like you can still see it in the NemoClaw doc: https://docs.nvidia.com/nemoclaw/latest/index.html

But that "Home" is completely optional thing and we can remove. I personally think it is intuitive enough that if you click the product name at the top you'd know you can go back to the landing page.
