Some of the hottest compost I had was when I brought home egg shells and coffee grounds from my workplace (McDonald's). Wow, it got can't-touch-it hot! I'd dump the morning's waste on top of the pile, then cover with dry leaves, straw, hay. It was more of a lasagna method.That's because there is a lot of leeway.It's possible, but not easy, to mess up compost. Use what you have that is plant material, or chicken poop, or coffee grounds, or shredded paper, or left over food....
Some things are "less good" than other things. If you're using an enclosed bin, you don't have to worry about attracting critters. Meat and bones can and will compost, but they might stink, and my open bin would get a bunch of possums or whatever rooting around in it.
As mentioned, avoid any diseased plant material, as the diseases can pass to the soil and infect the next year's plants.
