How to set up a Lemmy instance in a cloud server

I have been learning a lot thanks to Lemmy and the people behind it, so I wanted to contribute a bit back by making some easy-to-follow video tutorials.

I have also made the same video in Spanish: https://www.youtube.com/watch?v=h50M6jYZ8YU

As a beginner myself, I do have a level of concern that I might teach something incorrectly, or that I might expose others to security risks and liabilities. I hope that these concerns are not well-founded, but I am open to criticism!
