Information Security with HelmetJS-Running Locally

I’m on the very first lesson but I can’t figure out how to start the server on my local host. I tried “npm start” error: “Missing script start” , even though I see the script in the package json file . I tried app.listen, etc. How do I run the express server in this module? Thanks!!

My mistake, was in the wrong folder :scream:

However, my new error message states that express and helmet are not installed, though the assignment says its already installed.

UPDATE: I installed both and it runs fine.
