Experience with Mkdocs/Gitbook?

I narrowed down my search down to Gitbook or Mkdocs. They both seem to have their strengths. Of course Gitbook is integrated with Github, but Mkdocs can do so quite easily.
Do we have members with experience with both and have some suggestions for someone who is NOT a coder. I simply want to document a package used regularly on a server, which is presently stored in markdown locally, and maybe share with the world if it becomes useful enough to others.

Suggestions please…
