Embed document repository

I need to create a password-protected document repository—listings of documents by category—accessible to staff and board members. The password-protection is no problem, but mentioning for context.

Additionally, it needs to be extremely simple to administer. I have a Markdown-formatted list which would function as desired, except that in order to manage docs, the company site administrator would need to edit the Markdown code directly. This is not a functional long-term solution for the company.

Any ideas?
