Sure Deb. Here’s the long and short of it. THCA and CBDA are the acids that become the potent THC & CBD during typical combustion.
What decarb’ing does is convert the THCA & CBDA into THC & CBD without having to incinerate it so you can orally ingest it in it’s potent active state instead of it’s acid state which is not so potent.
So there are likely 100 times as many videos as there are methods.
I used to use the method from the MB2 manual but the 2 stage one I found online a few months ago seems to work better.
Here’s the one currently use. How much you want to break up your flowers is personal choice. I don’t bother until I grind it up all at the end.

Pre-heat heat oven to 225° F. once heated to temp I place the flowers in a single layer in a covered pan and bake for 20 minutes. I take it out turn the oven up to 240°F and let the flowers cool down to room temp. I then place the covered pan of flowers back in the oven for 40 minutes. Make sure it cools completely before removing the lid to avoid allowing delicious terpenes to evaporate.

If you’re decarb’ing a high CBD strain you can go 60-90 minutes instead of 40-60 to convert more CBDA to CBD.
I personally go for the lower time because I don’t use this stuff for pain. I prefer the benefit of the psychoactive components.
What you do with it from that point is up to you. If you plan on making oil and butter regularly, I suggest you invest in a MB2 machine. 1 hour to make oil and 2 hours to make butter.
It’s a great piece of equipment that really lends to a consistently delicious and potent product.
Otherwise you can scour youtube for more how-to
FYI - This is going to make your house smell beyond WONDERFUL and DELICIOUS. Cannabis potpourri anyone?!?
