Hi luke can you please review the changes I've made to the wiki and confirm
that I have done it 100% correctly? I also left questions on the wiki page for
you about somethings like the potential for voltage fighting.

Also I didn't want to remove the images you uploaded with the colours of the
wires for the ECP5 because I can't recreate them/correct them. Do you think we
should remove these images until after you can correct them?
