Want to cloth but need help

Bl

I've really been wanting to try cloth diapers but I need help, I know nothing about how it works or go about it or what I need or anything. Ftm, son is 5 months now.

What do I need? How do I put them on? Where do I put the diapers when changing in public? What's the best places to buy the stuff I need? How do you get the stains out? Just anything you could think of would seriously help out please!? 😞🙌🏼
