well, the edits isn't a 1,2,3 kind of thing. of course the notes PW provides aren't super informative, but not everything in PSA is grasped or discovered yet. and most likely since PSA is still in BETA form, no video will be made yet since no one is exactly sure what newer versions will have. it would just take a lot of time out of someone who isn't getting paid.
i know there is a basic one, but the power of PSA is all based on the user's understanding of it through trail and error, guides, or programming background.
the crazy things people have made either
A. took a long time to make it
B. trial and error
C. have a good background in programming already, so they already had a good understanding at what they were looking at
D. trial and error
E. all of the above
you'll just either have to wait, or try to figure it out yourself.
