-## Configuring the charset between the database and the application
+## Configuring the charset conversion
 This package offers to method to charset conversion, it can be converted in application layer or in database layer, we offered both methods because it can be useful for debugging, to config the application layer conversion you need to set up the following entries on the `database.php` file. You can view an example of the application encoding setup below:
 
 ```database
 'sybase' =>
     [
         'application_encoding' => true,
         'application_charset' => '',
-        'sybase_database_charset' => ''
+        'database_charset' => ''
     ],
 ```
+To use the database layer conversion add the property charset to connection configuration on the sybase configuration array
 
 ```charset
      'charset' => 'utf8',
 ```

 ## Configuring the cache
 As the library consults table information whenever it receives a request, caching can be used to avoid excessive queries
