Unclear what you're typing in, your formatting makes it very confusing.
Also motivate why you're typing in what you are typing in (what are you trying to do, what's the current situation, what change do you therefore need to do)
The instructions probably describe what to type in, and it looks like git is also telling you what format it accepts. You can also do a bit of research on your own by googling the thing you're trying to do, a decent first search query would be "git remote add"
You also ought to consider what action you're currently carrying out and what information you'll therefore need to give to git. The instructions, git, googling will all tell you that you're missing a really important piece, so important that the command doesn't make sense at all without that information - which is why considering what you're trying to do will make it obvious what that missing information is (and even if it's not, you've got all those other sources reminding you)
