+Using RBAC
+===========
+
+Lacking proper documentation, this guide is a stub copied from a topic on the forum.
+
+
+First af all, you modify your config (web.php or main.php), 
+```php
+'authManager' => [
+    'class' => 'app\components\PhpManager', // THIS IS YOUR AUTH MANAGER
+    'defaultRoles' => ['guest'],
+],
+```
+
+Next, create the manager itself (app/components/PhpManager.php)
+```php
+<?php
+namespace app\components;
+
+use Yii;
+
+class PhpManager extends \yii\rbac\PhpManager
+{
+    public function init()
+    {
+        if ($this->authFile === NULL)
+            $this->authFile = Yii::getAlias('@app/data/rbac') . '.php'; // HERE GOES YOUR RBAC TREE FILE
+
+        parent::init();
+
+        if (!Yii::$app->user->isGuest) {
+            $this->assign(Yii::$app->user->identity->id, Yii::$app->user->identity->role); // we suppose that user's role is stored in identity
+        }
+    }
+}
+```
+
+Now, the rules tree (@app/data/rbac.php):
+```php
+<?php
+use yii\rbac\Item;
+
+return [
+    // HERE ARE YOUR MANAGEMENT TASKS
+    'manageThing0' => ['type' => Item::TYPE_OPERATION, 'description' => '...', 'bizRule' => NULL, 'data' => NULL],
+    'manageThing1' => ['type' => Item::TYPE_OPERATION, 'description' => '...', 'bizRule' => NULL, 'data' => NULL],
+    'manageThing2' => ['type' => Item::TYPE_OPERATION, 'description' => '...', 'bizRule' => NULL, 'data' => NULL],
+    'manageThing2' => ['type' => Item::TYPE_OPERATION, 'description' => '...', 'bizRule' => NULL, 'data' => NULL],
+
+    // AND THE ROLES
+    'guest' => [
+        'type' => Item::TYPE_ROLE,
+        'description' => 'Guest',
+        'bizRule' => NULL,
+        'data' => NULL
+    ],
+
+    'user' => [
+        'type' => Item::TYPE_ROLE,
+        'description' => 'User',
+        'children' => [
+            'guest',
+            'manageThing0', // User can edit thing0
+        ],
+        'bizRule' => 'return !Yii::$app->user->isGuest;',
+        'data' => NULL
+    ],
+
+    'moderator' => [
+        'type' => Item::TYPE_ROLE,
+        'description' => 'Moderator',
+        'children' => [
+            'user',         // Can manage all that user can
+            'manageThing1', // and also thing1
+        ],
+        'bizRule' => NULL,
+        'data' => NULL
+    ],
+
+    'admin' => [
+        'type' => Item::TYPE_ROLE,
+        'description' => 'Admin',
+        'children' => [
+            'moderator',    // can do all the stuff that moderator can
+            'manageThing2', // and also manage thing2
+        ],
+        'bizRule' => NULL,
+        'data' => NULL
+    ],
+
+    'godmode' => [
+        'type' => Item::TYPE_ROLE,
+        'description' => 'Super admin',
+        'children' => [
+            'admin',        // can do all that admin can
+            'manageThing3', // and also thing3
+        ],
+        'bizRule' => NULL,
+        'data' => NULL
+    ],
+
+];
+```
+
+As a result, you can now add access control filters to controllers
+```php
+public function behaviors()
+{
+    return [
+        'access' => [
+            'class' => 'yii\web\AccessControl',
+            'except' => ['something'],            
+            'rules' => [
+                [
+                    'allow' => true,
+                    'roles' => ['manageThing1'],
+                ],
+            ],
+        ],
+    ];
+}
+```
