Here is my custom preferences for editors.

Edit: ~/.vimrc

set mouse-=a
syntax on
set paste
set autoindent
" With expandtab option set, if you want to enter a real tab character use Ctrl-V<Tab> key sequence.
set expandtab
set tabstop=4
set shiftwidth=4

Custom templates (github, monokai):

mkdir -p ~/.vim/colors
wget https://raw.githubusercontent.com/acarapetis/vim-colors-github/master/colors/github.vim -O ~/vim/colors/github.vim
wget https://raw.githubusercontent.com/BarretRen/vim-colorscheme/master/colors/monokai.vim -O ~/vim/colors/monokai.vim

To use new colorscheme by default add them to ~/.vimrc

colorscheme monokai
