How to get started with MBF21 Dehacked?

[MemeMind]

I have been seeing all the cool stuff being done with MBF21.
I would love to start messing with it but I dont know where to start.

Like is there a specific editor for it? 
I havent done some hand written dehacked before so do I have to learn that? I alwayed used Whacked for dehacked.
And really any other things I should know.
