daylight Diva functions

Hello I am new in grasshopper. I don't know how to start it.

I would like some help to learn the daylight diva functions.  Does  anyone have a tutorial about this to help me?

I am performing a rather large series of tests for academic purposes and if I would need to run a daylight analysis to get UDI and glare analisys. I am trying to do this only in Diva with Rhino but it is very  time consuming...

Any help would be greatly appreciated!!!!
