I'm following this blog tutorial to help complete an assignment (I'm doing a HTML/CSS/Javascript bootcamp, the assignment is for a functioning blog with certain characteristics), but there are several passages using the terminal, with which I have 0 familiarity. Around the 6th minute of the video, it shows to set up the server and than to check its functionality via both the terminal and the browser. His result is a blank page (as it apparently should be), whilst I keep gettin "Error: ENOENT: no such file or directory". Having no prior experience with the terminal, I don't really know what to do. I tried to follow various suggestions from other Stackoverflow similar questions but nothing works. I've been stuck here for hours and I'd really like to go ahead. As you could guess, I'm very inexperienced.

Please find below the screenshot of my VS code and of the problem.
