+# vim-pug #
+
+Vim syntax highlighting for Pug (formerly Jade) templates.
+
+For best results consider using this with an (improved) HTML5 syntax plugin.
+
+Installation
+------------
+
+I prefer to install plugins using Tim Pope's 
+[pathogen.vim](https://github.com/tpope/vim-pathogen).  Installation using
+pathogen is quite simple.
+
+    cd ~/.vim/bundle
+    git clone git://github.com/digitaltoad/vim-pug.git
+
+If you do not want to use pathogen.  You can always install vim-pug 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.
