Vim syntax highlighting for amber templates.
I prefer to install plugins using vundle.vim.
Plugin "therobut/vim-amber"
If you do not want to use Vundle, you can always use another plugin manager of your choice, or you can always install vim-amber in the normal manner by copying each directory to your ~/.vim directory. Make sure not to overwrite any existing directory of the same name and instead copy only the contents of the source directory to the directory of the same name in your ~/.vim directory.
