What are you looking for?
Sounds like you already decided the biggest which is if
DVC is right for you.
Now it comes down to:
Direct vs Resale
Which Resort
How many points (determined by budget, resort, room type, how often you go)
Then it's about Use Year after all the above is decided.
What exactly are you stuck on because honestly the best way to learn is simply taking it one step at a time IMO.
Then there is info on how to see going rates on resale, timelines on resale, title transfer, account access, how to book, how to pay dues, ect all of which really comes after deciding on those initial questions up top.
