Atom

Now, they are careful to note that Atom isn't strictly required for the web server to function, but it drastically improves your coding capability, like upgrading from a manual hand crank to a power drill.

That's a good analogy.

To get it, we transition back to a graphical browser on the Ubuntu desktop, navigate to atom.io, and download the Debian package file.

We then use our terminal to navigate to the downloads folder and install that package directly into the operating system.

And what you're doing here is bridging the gap between server administration and software development.
