I installed neovim
On OpenBSD, FreeBSD, Void Linux, Manjaro, Debian, Fedora and more..
I read an article found here.
This article is written back in 2015, a wee bit old as pointed out by kungtotte.
kungtotte – @iah buyer beware if you want to use Windows ever and use the same editor. Vim8 works a lot better on that platform and it supports async now too. It's fairly trivial to turn an init.vim into a vimrc or vice versa though, so I guess it's moot.
