Is there a documentation?

Is there documentation where the features and workflows are explained?
This would increase usability a lot.
For example a guide for installation, one for new users, and one for administrators and even developers who want to contribute to this project.

Nothing except the READMEs.

Then I want to transform this issue into a feature request:
Please add documentation for the points mentioned above.
