nvim configuration

init.vim

" Notes to make this all work
" ---------------------------
"
" 1) vim-plug - follow the directions at https://github.com/junegunn/vim-plug
" 2) a powerline patched font, I recommend this one https://github.com/ryanoasis/nerd-fonts/tree/master/patched-fonts/Meslo/M-DZ/complete
"    the OTF file will be fine, you don't need all the files in that dir, just choose one
" 3) a truecolour capable terminal like iTerm or Terminator ... or remove the
"    settings $NVIM_TUI_ENABLE_TRUE_COLOR and set termguicolors below
" 4) to install all the plugins below once this file is in place run :PlugUpdate
