Update content

[pabzm]

The docs are severely outdated. Most of the text might be still valid but needs proof-reading. The screenshots are all taken with the "larry" skin, and should be replaced in a newer version.

The old docs should still be available, and newer docs placed alongside of them in a new subdirectory.

Is there an interest in the team that people from the community take care of it?

We would appreciate any help, yes!
