I think I might not be understanding something in the instructions, am I supposed to copy the repository link directly, or am I supposed to do something else first?

Just rechecked, deckbuilder is working fine. Please re-read the About -> How to use section in the editor and follow the steps

I don't know what's up, but the deckbuilder doesn't seem to work properly, I don't know if I'm just not doing it right, or if it's just broken, but I can't even see the cards, let alone do much of anything.
