My amazing Neovim configuration.

" Download and install nvim, then install 'dein' the vim-package manager.
" During installation of dein it will output a sample configuration, take the
" two lines that `set runtimepath=PATH` and `dein#begin(PATH)` and replace the
" ones in this file online 14 and 17. Restart nvim and Happy Vimming!
