Basic Composting - Layers, Rules

I am wondering how to start composting in general. What are the basic layers or contents you need to get started? Is there a specific composting bin which has worked better than others?

I'd say the most important starting place is finding a good source of carbonaceous "brown" material - stuff like wood chips, dry leaves, shredded cardboard, shredded paper, shredded newspaper, dry pine needles, chopped up dried dead branches, etc.

If you can get enough carbon collected consistently, that's you first 80% of the battle won 💪

I've been putting my cardboard boxes through a 12-sheet micro-cut shredder, that's working great and giving me most of the carbon I need. What kind of "browns" do you have available to you and abundant?
