Finally more documentation is available.
We wrote a FAQ and a features list for hikr. For the moment is only in English and still not fully completed, but already much more that what we had; help in translation would be great. You can read it here: www.hikr.org/post6340.html
We also reorganized the presentation of the Help section, as you can see here. I tried now to translate this page into German, corrections (surely there are a lot of errors) would be of great help.
