 Simple Bandwidth Scanner Configuration Files
 ============================================
 
-Sbws has three config files it reads: two general, and one specific to logging.
-They all get combined internally to the same ``conf`` structure, so technically
-you can put any option in any file, but you need to pay attention to the order
-in which they are read. Options specified in multiple files will take the

-you are meant to put them in.**
+How to create user customized configuration files
+--------------------------------------------------
+``sbws`` use internal configuration files.
+These are **not** intented to be modified by a user.
+If a user needs a customized configuration file, the user needs to create it.
+There's an example configuration file with the minimum data that a user
+probably needs to edit in ``examples``. For more advanced configuration options see
+documentation below.
+``sbws`` will check by default whether there's a user customized file in
+``~/sbws.ini`` and use it when it exists.
+The user can store a customized configuration file anywhere else in the file
+system and and provide ``sbws`` with the path to it via the ``-c`` or
+``--config`` cli option.
