#Policies
  
  ## Setup
  
  To interact with the policies of a scaling group, you will need to setup the group object beforehand.
  
  ```php
  $groupId = 'foobar';
  $group   = $service->getGroup($groupId);
  ```
  
  For more information about setting up the `$service` object, please see the userguide tutorial for [Autoscale groups]().
  
  ## Get all policies
  
  ```php
  $policies = $group->getPolicies();
  
  while ($policy = $policies->next()) {
      // do something
      echo "{$policy->name} {($policy->type)}" . PHP_EOL;
  }
  ```
  
  ## Create a new scaling policy
  
  Creating policies is achieved through passing an array to the `create` method.
  
  ```php
  $policy = new \stdClass;
  $policy->name = "NEW NAME";
  $policy->change = 1;
  $policy->cooldown = 150;
  $policy->type = "webhook";
  
  $group->getPolicy()->create(array($policy));
  
  // or even:
  
  $group->getPolicy()->create(array(
      (object) array(
          'name' => 'NEW NAME',
          'change' => 1,
          'cooldown' => 150,
          'type' => 'webhook'
      ),
      // etc.
  ));
  ```
  
  ## Get, update and delete a scaling policy
  
  ```php
  $policyId = 'foobar';
  $policy = $group->getPolicy($policyId);
  
  $policy->update(array(
      'name' => 'More relevant name'
  ));
  
  $policy->delete();
  ```
  
  ## Execute a scaling policy
  
  ```php
  $policy->execute();
  ```
