I’ve edited your post for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.
You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.
I know it might seem a little weird, but you don’t want any content inside the list at this step, just the unordered list tags.
Your list tags aren’t quite correct. The tag is a lower case u followed by a lower case l (which stands for unordered list). You have accidentally used the number 1 instead of a lower case l.
P.S. I agree that the lowercase l in the instructions does look like the number 1. Perhaps it’s not the best font to use for code examples? There might be better monospaced fonts to choose from. If I get a chance I’ll look into this and open an PR if I can find a better one that is less ambiguous.
