How do I run commands like install npm in a console for a project website i downlaoded ?

How do I run the np install command in the console ?​Hello pretty people. I downloaded a project on github and uploaded it on my Node.js (localhost) server. Script is not running at all. Creator says I have to run these commands, I do not know how to do it. I type them in the console and nothing happens. When I enter on the website I see a blank page and the JS is not loading. How do I run all these for the script to work ?# install dependenciesnpm install# serve with hot reload at localhost:8080npm run dev# build for production with minificationnpm run build# run unit testsnpm run unit# run e2e testsnpm run e2e# run all testsnpm test
