How to setup supabase auth for non-developer

I’m trying to setup Supabase auth with my project, but I’m not a traditional developer. Using github and managing files is foreign to me, so tutorials online are still confusing to me.

Would anyone be open to hold my hand through the setup?

I’ve pushed my project to github from the Plasmic editor, but I really don’t know where to go from here. I will eventually be hosting the app on render.com

Thanks in advance for any help!
