How to start potty training?

Have any of you mommas had any success with the 3day potty training ?
Pros & Cons ?
Tips for success. My little guy has been showing signs of interest for 2months now . I’ve introduced it to him , he’s used the potty and knows how to flush and that he washes his hands afterwards. And gets praised if he does use the potty.
But we’re ready to get out of diapers .
Any tips or suggestions is appreciated!
