[Suggestion] Embed docs into the binary

[fabricionaweb]

Hi, would it a good idea to embed the docs into the build/binary?
This way it would produce a single binary that does not need/depends on the "docs" static files

Just a suggestion that I think makes it easy to run and to package the project.
