About the Book
I'm going to cover how to build Moodle module - also called "activity". While doing so, we will go through most of the Moodle building blocks. I'm not covering any other plugin types (blocks, filters, reports...) explicitly but after studying this book and a bit of extra research you should be comfortable with development of any Moodle plugin type.
