Just take the bare minimum and spend a night near your car or home, someone you can up and leave at 2am if you need to. Take a shit before you go.

There’s not really any surprises for what you need, just take a tent, sleeping bag, warm enough clothes, a little toilet paper, water and food (just take loads of cereal bars and stuff you don’t need to cook for the first time). The only other thing to take is bin bags so you can clean up any mess you make. You should leave the place you camp as if you were never there. No food on the ground, nothing. Don’t feed the animals.

If you’re feeling extravagant you can take some baby wipes and toothpaste/toothbrush for cleaning but don’t stress yourself on the first time. If you have a garden you can even camp in your garden for the first time just to get a feel for it.
