We can't offer help in English for the other plugins yet, sorry. You may want to have a look at the German documents and see what your browser's translate function comes up with.
Unfortunately, this document is no longer entirely up to date. You can find a more recent help document in German here.
Note
If something doesn't seem to be working the way it should, kindly let us know. This can be a huge help!
Please document the problem and send an email to Ulrich Kaiser.
