Any Guide on how to use the cloverHDMI guide? It's unreadable to me.

I appreciate the work of Toleda in creating the script, but I think the guide is not very well written. It assumes you know what's going on already, and skips important words useful to newbs like me.

So anybody can give me a hand? I mounted the EFI partition and ran the script. All I got is "No audio codec detected No system files were changed"

But I'm not really sure what I'm supposed to do. Thanks.
