Please help!!!

So I finally got the money to get an h23 vtec

I'm wondering about the swap is it pretty much drop in and ECU?
or is there more to it

I've looked it up and would like a simple answer and info (not sounding rude)lol

just need to know if I'm missing anything or if everything just hooks right up

I've looked this up on internet and people have said different things
thanks this will be my first engine swap btw
