 ----
 ## Usage
 Add *Bindable* as a trait on the target classes.
-
-
-    use Bindable;
-
-
+```php
+use Bindable;
+```
 Implement the *getKeys()* method so the bind method knows how the array is keyed.
-
-
-    public function getKeys()
-    {        
-        return array_keys($this->data);
-    } 
-
+```php
+public function getKeys()
+{        
+    return array_keys($this->data);
+} 
+```
 Create a get method suffixed by the name of the target attribute which is passed a singular key from the *getKeys()* method and returns a reference to the desired position in the array.
-
-    public function &getAge($person)
-    {
-        return $this->data[ $person ]['Age'];
-    }
+```php
+public function &getAge($person)
+{
+    return $this->data[ $person ]['Age'];
+}
+```    
 Finally, call bind and pass through the second object and the key which the bind should occur on.
-
-    $people->bind($preference, 'Age');
-
-These methods should be implemented in both classes.
-
+```php
+$people->bind($preference, 'Age');
+``` 
+These methods should be implemented appropriately in both classes.
