I hope this is the right section for this. I recently discovered Easy Diffusion so I've moved to running SD locally on my own PC, but I'm having some issues getting the most out of it. It's hard to find good articles online that describe in plain, simple text how to do much of anything; most of them boil down to "To do this, just do it" which is frankly beyond useless. I'm trying to find good, concise help for the following few things:

-A good refresher or explainer on how the features work. I've gotten to where I am by simply looking at other prompts by people and making my own by cobbling them together. It works, but I know it could work better if I actually understood what I was doing.

-A simple how-to for training your own models/LoRAs. Every article I've looked at was written for the benefit of machines, it seems like. They tend to either be the same "to do it, just do it" pieces or stuff written for those who clearly already know what they're doing.

Basically I've been using AI to generate commission references I can give to a proper artist later. It's hard to commission work of characters who haven't been drawn before, and I've had poor experiences in the past with submitting written descriptions. Either there's a language barrier or it leads to a lot of unnecessary back-and-forth with the artist making them tweak or redo things which is not fair to them. If I can just show a few picture references I've made, it ensures I get what I'm looking for and the artist has an easier time.

I've seen that @skyrbrian seems to be the subject matter expert, but thanks in advance to anyone who replies!
