Install Octoprint on Rasbian StepbyStep?

Hallo, is there a StepbyStep guide to install Octopi on a pre-installed current Rasbian?

The Octopi manual itself is very poor and only produces error messages.

Hi @Benedikt_K!

There is this thread by @foosel: Setting up OctoPrint on a Raspberry Pi running Raspbian

And in this video . Chris explains how to install OctoPrint on Linux.
