--- Interface settings
+## Interface settings
 
 The recommended place to store global interface settings is the ini style global config system 
 (see system.ini.master file in install/tpl/ to set defaults). The settings file 
 gets stored inside the ispconfig database. Settings can be accessed with the function:
 
+```
 $app->uses('ini_parser,getconf');
 $interface_settings = $app->getconf->get_global_config('modulename');
+```
 
 where modulename corresponds to the config section in the system.ini.master file.
 To make the settings editable under System > interface config, add the new configuration
 fields to the file interface/web/admin/form/system_config.tform.php and the corresponding
 tempalte file in the templates subfolder of the admin module.
 
--- Server settings
+## Server settings
 
 Server settings are stored in the ini style server config system (see server.ini.master template file)
 The settings file gets stored inside the ispconfig database in the server table. Settings can be 
 accessed with the function $app->getconf->get_server_config(....)
 
 Example to access the web configuration:
 
+```
 $app->uses('ini_parser,getconf');
 $web_config = $app->getconf->get_server_config($server_id,'web');
+```
