Blockchain Developer course

In the blockchain developer course by Sean Han:

Im having trouble using the nmp install from the github repo described, after creating the blockchain-cli file the npm just will not lead me to success as described in the post. Can someone advise?

September 2017 was 4 years ago. I would assume that those instructions are pretty out of date.

Did cross my mind, had to ask the question, just in case. Yes I’ll take that, thanks Jeremy
