Just wanted to let everyone know that there's completely new Concrete5 5.7 developer documentation available [http://www.concrete5.org/documentation/developers/5.7/](http://www.concrete5.org/documentation/developers/5.7/) We will be adding to it regularly, and whenever we do I'll update the recent additions sidebar, as well as post about it here. The designing with Concrete5 section should be mostly completed, and now we've shifted focus to complete and thorough documentation about building block types and working with existing block types. Stay tuned!
