 Restricted administration rights
 ================================
 
-The module makes impossible for administrator to set (and see) more access rights (groups) than he already has.
-The only partial exception of this rule is made if you are already a member of the 'Allow add implied groups from settings' security group.
-Then you are allowed to escalate your privileges but just from ``Settings`` menus (by means of ``group_XXX`` boolean fields of ``res.config.settings`` models views).

-This doesn't affect superuser, of course.
+It also using for restrict changes to certain settings for specific users, who should be prevented from making important changes without the knowledge of the superuser.

 Typical usage of the module.
 ----------------------------
 
-The superuser creates an administrator user without access group "Show Apps Menu" (see **access_apps** module). Then the administrator has access to settings, but not able to install new apps (without this module he can add himself to "Show Apps Menu" and get access to apps).
+This example in addition to this module installed also requires **base_setup** and **access_apps** modules.
+
+1. The superuser creates an administrator user with empty parameter  **"Apps access"**.
+2. Then the administrator has access to settings, but not able to install new apps.
+
+* Without this module this user can add himself to **"Allow installing apps"** access group and get access to apps management.
