Hey, this is really simple to use just put the html code in any online html editor(https://www.onlinehtmleditor.net/) is the one i recommend.

step 1 - copy this code, if github is blocked you can go here - - https://www.dropbox.com/scl/fi/x2gyu6seh4or8mifrobqo/index.html?rlkey=gfjdy12i4srz7hmk7irsxii62&st=pt2k0xjr&dl=0

step 2 - just follow the instructions
