This page is work in progress documentation for Civi Rules.
Civi Rules is based on the Drupal Rules module and does react on an event (post create contribution) and executes a certain action when certain conditions are met.
This page will contain what we have thought of what needs to be done to develop such an extension. Rather than just starting (what we have done with trigger-action extension) this one is a bit more thought of. So this description is also a basic for a wider debate on how things should work.
