How does this work?

I came looking for a YouTube version of Bronn Journey's Infant Holy, and it appears I can create one myself? But the proffered videos are all of other artists. I'm not sure what the purpose is here, or how to achieve it. Is there a "How to" page?

This site isn't for creating videos. The main goal is to track cover versions of songs. The video feature lets you add videos of a performance. More info can be found at https://secondhandsongs.com/page/FAQ
