-## A Quick Note on Regexes
 
-Vim 7.4 was released recently, and unfortunately broke how this plugin
-handles regexes. There was no real easy way for us to fix this unless we
-completely rewrote how regexes work.
+## Installation
 
-Good News: There was a recent update to Vim 7.4 that fixes this issue.
+### Install with [Vundle](https://github.com/gmarik/vundle)
 
-Make sure you are at least using Vim 7.4, with patches 1-7.
+Add to vimrc:
 
-If you are stuck on an older version of Vim 7.4 with no way to update,
-then simply perform the following commands to fix your current buffer:
+    Plugin 'pangloss/vim-javascript'
 
-```
-:set regexpengine=1
-:syntax enable
-```
+And install it:

+## Configuration Variables
 
 The following variables control certain syntax highlighting features. You can
 add them to your `.vimrc` to enable/disable their features.
 
-#### javascript_enable_domhtmlcss
+```
+let g:javascript_enable_domhtmlcss = 1
+```
 
 Enables HTML/CSS syntax highlighting in your JavaScript file.
 
 Default Value: 0
 
-#### b:javascript_fold
+-----------------
 
-Enables JavaScript code folding.
+```
+let g:javascript_ignore_javaScriptdoc = 1
+```
 
-Default Value: 1
+Disables JSDoc syntax highlighting
 
+Default Value: 0
 
-#### javascript_ignore_javaScriptdoc
+-----------------
 
-Disables JSDoc syntax highlighting
+```
+set foldmethod=syntax
+```
 
-Default Value: 0
+Enables code folding based on our syntax file.
+
+Please note this can have a dramatic effect on performance and because it is a
+global vim option, we do not set it ourselves.
