There are some basic command line commands you’ll want to Google and learn, but for this tutorial you only need a few:
ls = list files and folders in current directory
cd = change directories
vim, emacs, nano = a text editor
Type: ls to see where you are; you should see a directory called “public_html”
Type: cd public_html to browse into that folder
Type: ls to see where you are; you should see your index.html file
