How to use dashboard template?

I’m trying to use the dashboard from GitHub - matt8707/hass-config: ✨ A different take on designing a Lovelace UI (Dashboard) and can’t figure out how to install it. I followed the steps hass-config/ at dbfed2fedc8992d79f9dca142dd01ebfc1766f18 · matt8707/hass-config · GitHub but got lost when it said “Manually copy over these files from matt8707/hass-config

What do I do?
