But how do you install dependencies? Is the "it" you're scping a folder structure that includes them?

Dependencies are managed by Composer (like npm, cargo, etc) for more than 10 years now.

I was replying to the previous comment - how does this relate to that?

You asked how you install dependencies, they answered that question.
