+# Blade Alternate
+
+Blade Alternate is a small extension to blade that adds the common operation of changing values throughout a loop. Now thats a horrible description, so heres an example:
+
+    @foreach($users as $user)
+    	<tr class="@alternate('odd', 'even')">...</tr>
+    @endforeach
+
+Which would result in alternating rows of a table, with the class switching between odd and even every time. This works with any number of arguments, for example, you might see a image gallery with three columns.
+
+    @foreach($images as $image)
+    	<img src="{{ $img->url }}" class="@alternate('left', 'mid', 'right')" />
+    @endforeach
+
+## Installation
+
+Add `adenfraser/blade-alternate` to `composer.json`.
+
+    "adenfraser/blade-alternate": "1.0.*"
+
+Run `composer update` to pull down the latest version of Blade Alternate. Now open up `app/config/app.php` and add the service provider to your `providers` array, *after* the ViewServiceProvider.
+
+    'providers' => array(
+    	...
+    		'Illuminate\View\ViewServiceProvider',
+    		'AdenFraser\BladeAlternate\BladeAlternateServiceProvider',
+		...
+    )
