Any beginner guides on Johnny for +R?

Picked up the game two days ago, I'm not really new to fighting games but I've never wanted to play seriously. Johnny's cool as fuck and I've decided to main him.

Considering the game doesn't really have a tutorial,are there any beginner guides for Johnny or just the game in general?

Don't get me wrong,Dustloop is really nice,but it can be a bit overwhelming.

Thanks in advance!
