Documentation
Unfortunately, the documentation on M3Actions is poor at the moment. Although this website is the first attempt to provide a basic set of introductionary material, we hope to extend this section over the next month.However, a good idea to start with is to have a look at the examples section. You'll find some basic examples as well as more sophisticated usages of the action language and the whole framework.
