Online service for writing a manual/documentation?

Question

Documentation

Could you tell me a free online service for writing a manual / documentation?

Answer 1

https://paper.dropbox.com/ - still in beta, but they promise a lot of features (including great snippets for showing the code)

Answer 2

Like this? https://readthedocs.org/ You get something like this peewee.readthedocs.org

Answer 3

I don’t know what you expect from such a service, so that he does everything for you? In my opinion, everything can be written on Google Docs. Open some kind of manual and, by analogy, make your own.
