Hmm, thats a good question.
A "Getting started" could be done in a *.txt file, but a 'real' doc shouldn't be done as *.txt .
It's a question what kind of doc is needed. People who played Warcraft or C&C or some other real time strategy game will be able to handle Glest without any help, i think.
We should ask some developer, what kind of doc they want to have and IF they want it to be part of the next release....
It's only an idea now, but I allready started working.
I'm sure, they would publish ANY documentation as an "additional download" if its good (they would be foolish if the do not).
But it would be an extra motivation if we could make a competition and the best one could be the 'official' Glest doc, part of the Glest package like the "readme.txt" .
