Suggestion for uber-juno setup instructions

I followed the instructions here:

However, there was an additional required step that is not listed. When I tried to run Julia in Atom, I received the error message below. It appears that the Atom package must be installed via the REPL before I could use Julia in Atom.

Perhaps the solution is self-evident, but why not add this step to the instructions?

Starting Julia…
