I want to use my PC to host files and photos and be able to view them from anywhere, and after some searching, people recommended nextcloud.

However, the issue is that I've never used linux or have any experience with it. Is there a simple guide for an idiot like me to be able to set up one? I've tried to look one up myself, but every guide is completely different and some are older than others, and I'm not sure which one should I listen to.
