whole guide about using some gphoto software, yet not a single link in article

btw it's only for Linux, so don't even bother reading the linked web, if you are in windows

http://www.gphoto.org/

Correct title:

How to use your DSLR from 2008 as a webcam IN LINUX in 2022 (NixOS)

I wished people would not omiss such important information in title when writing articles or linking them wasting everyone's time including server traffic
