What is "Source Control"?

JellyCORE

Hello there! ^^

I'm not entirely sure if this is more suited to the "Brackeys' Tutorials" section, but I think Source Control is something outside of that, as well, so I'll just ask here!

In Brackeys' video "HOW TO GAME JAM!", GitHub and Unity Teams were mentioned as useful platforms for "Source Control".

What exactly is Source Control?

Thank you very much for your help! <3

Actually, apologies, I completely forgot to search this up on the internet ^^'

Found an answer! Thank you, anyhow!
