 Custom types
 ============
 
-In order to exclude configuration errors, custom datatypes for IP addresses and sizes are introduced.
+In order to exclude configuration errors, custom datatypes for IP addresses and sizes (constrained integer) are introduced.
 
 For assigning an ip address simply assign a string with the desired address. 
 Decimal and hexadecimal format is supported. 
 In case the ip address is not valid, the type will throw a std::invalid_argument exception.
 
-You can use the ip address like a normal string object. For example:

 Initialization of the configuration
 ===================================
 
-The configuration will be first initialized with the default .ini file found in the system. 
-In case the .ini to use is specified vial command line parameter, this one is chosen instead.
-If it cannot find any .ini file, default values will be used for the first initialization of the configuration.
+The configuration will be first initialized with the default values specified by eCAL.
+If you want to use the systems eCAL .ini file, call the InitConfigWithDefaultIni() function of the config object.
+
+In case the .ini to use is specified via command line parameter, this one is chosen instead. 
+The object will throw an error, in case the specified .ini file cannot be found.
+
+It is also possible to specify the .ini by calling the function InitConfig(std::string _ini_path) of the config object.
