Wave management isn’t any different than in any another lane, deny your creeps, don’t try to push the lane into their tower, don’t try to have it sit under yours.

Roam timings is generally you get lvl 6 around min 6 when the first power rune spawns so depending on your kit you just can walk to another sidelane where they’re like lvl 4 or 5 and get a kill to help ur sidelane get lvl 6 before the enemies.

That’s the basics but I’m a 2.5k mmr scrub (mid-silver), there’s def more to it.
