To install a style just place its XML file into a folder of the style search path.
A typical search path for GtkSourceView version 2 looks like:
~/.local/share/gtksourceview-2.0/styles//usr/share/gnome/gtksourceview-2.0/styles//usr/local/share/gtksourceview-2.0/styles//usr/share/gtksourceview-2.0/styles/
If this does not work in your distribution you can find out your style search path with this python script. To run it you need the python bindings for GtkSourceView 2. In Debian-based distributions this is package python-gtksourceview2.
A typical search path for GtkSourceView version 3 looks like:
~/.local/share/gtksourceview-3.0/styles//usr/share/gnome/gtksourceview-3.0/styles//usr/local/share/gtksourceview-3.0/styles//usr/share/gtksourceview-3.0/styles/
Place monokai-vim.vim in the colors directory of .vim/
Place monokai-emacs.el in the themes directory of the .emacs.d/
Import the plugin
Import the preferences
