-Update, it is highly recommended to checkout the rails3 branch. As soon as possible I will merge this branch
-into master. So for beginnners, better start with the new (I hope much easier) code.
+Have a look at [README_DEVEL](https://github.com/foodcoops/foodsoft/blob/master/doc/DEVELOPMENT) (possibly outdated) and the (more recent) [Developing](https://github.com/foodcoops/foodsoft/wiki/Developing) page on the wiki.
