Of course, "also" means "in addition". I was wondering what I'd do with helm-dash on GNU/Linux if Dash is only for Mac.

The helm-dash repo tagline on GitHub says "Browse Dash docsets inside emacs", so I quickly dismissed it as I don't use Mac.

Reading a bit further, now I see that it doesn't need Dash to be installed. So that's great! I'll see if an ivy/counsel version is out there.
