How to install discourse

Hi can somebody point me in the right direction
I have dietpi installed with nextcloud and apache
Now I want try to install discourse forum
Does any one a tutorial for me please?

A wierd questions. Simply check the official Discourse install guide. discourse/INSTALL.md at main · discourse/discourse · GitHub

Make sure to have Discourse running on a different port than 80 as this one is already used by nextcloud web server.
