Ask HN: Document/content management system for brick and mortar store?

Howdy!

I'm looking for "the best" SaaS tool out there to help me host documentation for a brick and mortar store.

Think: operational manuals and procedures, various documents like contract templates, forms, etc.

Ideally, it should offer wiki-like page editing with embedded images, maybe graphs and videos and also documents hosting such as word files, PDF, etc.

For APIs and technical documentation there are a lot of options (readthedocs, readme.io, confluence and others), but not so much (that I could find) for non-technical documentation.

I have looked into Sharepoint online and WordPress with some plugin, but would appreciate input from people with more experience in the subject.
