Step 1 - Download Atom.io
I downloaded the deb installer direct from Atom's Github releases page. You'll need to use the correct flags in your curl command in order to handle the inevitable redirects :: le sigh ::
Step 2 - Install Atom.io
Installing is simple as opening your file browser, navigating down to My files > Linux files, then double clicking the deb installer file.
Step 3 - Launch Atom
I prefer to launch directly from the directory I want to work from using the
atom . command. Although, you could also just search for Atom and launch that way.
