The http://community.kde.org/KDE_Mobile/Harmattan site gives some insight about the outcome of the recently happening KDE Harmattan Sprint in Berlin. The documentation on that site has been growing continously, and non-native speakers, like me, also put things there.

The task is to go through the wiki and fix the mistakes, like typo, grammar, ambiguity and so on. If you can ping me on freenode ("djszapi") there, that helps a lot with the task. Hope you can do that. :)
