I've just got it now: your doc uses parts of the innovative wiki! But the Welcome Site of the doc is all of this, what is in German. I was beginning to edit a linked english page for translating into German. But then, my thought was: don't you overwrite the english page, if you overwrite that now with your not-for-english-folks-understandable German? Oh yes, I do. So I've dropped it.
And now my question is: How to make a translation of the doc?
