 Composer - Package Management for PHP
 =====================================
 
-Usage
------
+Composer is a package manager tracking local dependencies of your projects and libraries.
 
-Todo
-----
-- Implement Repository & Package Backends (Git, PEAR, ...)
-- Make other system dependencies available as unremovable packages
-- Create compose CLI tool
+See the [about page](http://packagist.org/about) on [packagist.org](http://packagist.org/) for more information.
+
+Installation / Usage
+--------------------
+
+1. Download the [`composer.phar`](http://packagist.org/get/composer.phar) executable
+2. If you're on a \*nix system, make it executable: `chmod +x composer.phar`
+3. Create a composer.json defining your dependencies. Note that this example is
+a short version for applications that are not meant to be published as packages
+themselves. To create libraries/packages please read the [guidelines](http://packagist.org/about).
+
+    ``` json
+    {
+        "require": {
+            "monolog/monolog": ">=1.0.0"
+        }
+    }
+    ```
+
+4. Run Composer: `php composer.phar install` (on \*nix you can omit the leading `php`)
+5. Browse for more packages on [Packagist](http://packagist.org).
