We use outline (https://github.com/outline/outline) at work and it works pretty well for us. It supports collaborative editing, which was the main reason we went with it.

Personally, I use bookstack (https://github.com/BookStackApp/BookStack) at home. Mostly because I really like the mental model of using Bookshelves, Books, Chapters and Pages to sort my notes in.

My biggest beef with Outline is that I can initially use Markdown, as soon as it is saved, you cannot see the raw markdown again for editing.
