Web Scraping Homework 2 - Running After Clone

How do I run the code from https://github.com/15Dkatz/official_joke_api after I clone to it where I want to run it locally? I see it says to put in the code

• npm i && npm run dev

after I clone the code but then I get 'npm: command not found' in Git Bash. Is there some fundamental information that I am missing to make this work?

Thanks!
