Calendario: A jQuery calendar plugin for creating flexible calendars

This looks great but how does it compare to FullCalendar? [1]

From what I can see there is zero documentation, an area which FullCalendar excels at.

It will be hard to use this plugin without any documentation, certainly in the areas of events, which data sources are supported, etc.
