Comment 14 for bug 536467

#11: Seeing the build help of a building without having built it is very sensible. I think there is currently no way to check what workers an upgraded building needs.

#12: The user einstein13 has created some in-depth thoughts, you can find it under http://student.agh.edu.pl/~rak/widelands/. The strategy part contains some interesting ideas.
This is only plain text, so everyone can write something like that (without programming skills). In our wiki, everyone can create a new page. I think that is the easiest way to create such a content. Later on, we can simply reference to it.

#13: Please have a look at bug 350465 and bug 1336863. The later one describes some problems and why the Wiki is not up-to-date anymore.

In general, I think we need the help at least in two places: In the game and at our wiki (to keep the page open and continue playing and to look something up without starting the game). I doubt it is necessary to ship the stuff via pdf - a simple link to our wiki should be enough.

Btw, do you know "Battle for Wesnoth"? It has an awesome in-game help (with links) and offers the same information on their website.
