I've never released stuff for Unity before, I've only been using it for a 5-6 months, so this is kind of new to me still. I'll prob make it an asset package later

I just meant exporting it as a package within your repo (https://docs.unity3d.com/Manual/HOWTO-exportpackage.html). You right click > Export Package... and then select all the files for the package. Unity zips it up nicely into an asset that's easier to import.
