best procedure for door install

[Hair]

I'm fixin to put my doors back on. Never done it before.
My plan:
Bolt hinges to door, setting them at the middle of the slots.
Set door in cab (put a paint paddle under the bottom to hold it up off the rocker?)
Hold it and get the gaps looking like I like, and then tighten the hinges up on the cab.

I can see a million things going wrong with this process

I don't know... what's the best procedure for putting a door on and getting it aligned?
