 Minify is an HTTP server for JS and CSS assets. It compresses and combines files
 and serves it with appropriate headers, allowing conditional GET or long-Expires.

-Installation
-------------
+## Installation
 
-Installation requires PHP 5.3+, SSH access, and access to tools like `git` and `composer` or the privileges to install them.
+See the [install guide](https://github.com/mrclay/minify/blob/master/docs/Install.wiki.md).
 
-```bash
-cd /path/to/public_html
-git clone https://github.com/mrclay/minify.git min
-cd min
-composer install --no-dev
-```
+## Configuration & Usage
 
-What this does:
-
-1. Inside your DOCUMENT_ROOT directory, we clone this repo. Otherwise you may [download](https://github.com/mrclay/minify/archive/master.zip) and extract the zip file.
-1. We rename this directory `min`. E.g. You will have something like: `/home/example/public_html/min`
-1. We `cd` into it and run `composer install` to install the dependencies.
-
-You can verify that it is working by visiting these two URLs:
-    
-    * http://example.org/min/?f=min/quick-test.js
-    * http://example.org/min/?f=min/quick-test.css
-
-If your server supports mod_rewrite, this URL should also work:
-
-* http://example.org/min/f=min/quick-test.js

-Warnings
---------
+## Warnings
 
 * Minify is designed for efficiency, but, for very high traffic sites, it will probably serve files slower than your HTTPd due to the CGI overhead of PHP. See the [FAQ](https://github.com/mrclay/minify/blob/master/docs/FAQ.wiki.md#how-fast-is-it) and [CookBook](https://github.com/mrclay/minify/blob/master/docs/CookBook.wiki.md) for more info.
 * If you combine a lot of CSS, watch out for [IE's 4096 selectors-per-file limit](http://stackoverflow.com/a/9906889/3779), affects IE 6 through 9.
 * Minify *should* work fine with files encoded in UTF-8 or other 8-bit encodings like ISO 8859/Windows-1252. By default Minify appends ";charset=utf-8" to the Content-Type headers it sends.
