How do people know how to hang themselves?

I feel like if I was super depressed trapped in a jail cell or even just my house I'd have no clue how to kill myself in this manner.

It doesn't appear to be the most intuitive thing yet people around the world regularly perform it alone and succeed. Do people just hear about other people doing it and try to replicate it?
