Using ripgrep in Emacs using helm-ag (Spacemacs)

Why

Ripgrep is a fast search tool like grep. It's mostly a drop-in replacement for ag, also know as the Silver Searcher.

helm-ag is a fantastic package for Emacs that allows you to display search results in a buffer. You can also jump to locations of matches. Despite the name, helm-ag works with ripgrep (rg) as well as with ag.
