 ### Composer
 
-### Download, extract and copy
+Aoe_Scheduler is registered on [Packagist.org](https://packagist.org/packages/aoepeople/aoe_scheduler) so you don't have to add any additional repositories to you composer.json file:
 
-[Download zip or tar.gz](https://github.com/AOEpeople/Aoe_Scheduler/releases)
+Install Aoe_Scheduler using the [Hackathon Composer Installer](https://github.com/magento-hackathon/magento-composer-installer) - Read [Option 4.a in this blog post](http://fbrnc.net/blog/2014/11/how-to-install-a-magento-module)
 
-Compatible with hackathon installer (or aoepeople installer).
+```json
+{
+    "minimum-stability": "dev",
+    "require": {
+        "aoepeople/aoe_scheduler": "1.0.*"
+    }
+}
+```
 
-Show snippet
+If you want to use the AOEPeople Composer installer instead (and manually run modman afterwards) use this snippet (Read [Option 4.b in this blog post](http://fbrnc.net/blog/2014/11/how-to-install-a-magento-module)):
 
+```json
+{
+    "minimum-stability": "dev",
+    "require": {
+        "aoepeople/composer-installers": "dev-master",
+        "aoepeople/aoe_scheduler": "1.0.*"
+    }
+}
+```
 
+### Download and extract
 
+Of course you can also [download the zip or tar.gz file](https://github.com/AOEpeople/Aoe_Scheduler/releases) and extract it into your project webroot. While this is **not recommended (especially not on a production environment!)** this might be the easiest way to test Aoe_Scheduler if your not familiar with Composer and modman and don't feel like exploring it (you should! :)
