We use confluence. To overcome the issues some other people have mentioned (namely, lack of version control), our confluence docs are generated from version controlled markdown docs. It’s integrated with our build system so it doesn’t require much thought, you get the benefits of having your documentation living with your code, and you generate a doc that’s easily searchable and shareable for non-engineers. The only thing that sucks about this setup is that you can’t fix typos without making a diff :)
