Advice/tips/guides for a new scout?

So, finally decided to pick the game up recently, and really enjoying it. But, I do have to admit, I'm a little rusty with shooters in general, and the scout role is pretty chaotic sometimes.

Anyone have advice/tips/reliable guides they prefer for the scout class specifically?

What kinds of things do scouts do, especially newbie ones, that kinda bug you? What are the things a really good scout does that marks them as a really good scout?

So far, I find myself focusing kinda heavily on combat just because it's an obvious thing I can do, and zipping behind a bug to blast it in the ass with a shotgun is really fun. I assume that's not really my #1 job though. I keep our cave lit up pretty reliably, but should I be doing more ... actual scouting I assume?
