 Disable Security Groups in OpenStack ML2 Setup
 ----------------------------------------------
 
+Please **NOTE** that although Security Groups feature has been disabled automatically
+through ``local.conf`` configuration file by some installers such as ``devstack``, it is very likely
+that other installers such as ``Apex``, ``Compass``, ``Fuel`` or ``Joid`` will enable Security
+Groups feature after installation.
+
+**Please make sure that Security Groups are disabled in the setup**
+
 In order to disable Security Groups globally, please make sure that the settings in
 **OPNFV-NATIVE-SEC-1** and **OPNFV-NATIVE-SEC-2** are applied, if they
 are not there by default.
