 /**
  * @brief This datatype is used to identify different connection over a single interface
  *        (like RMAP or I2C)
  * @details
- * To use this class, implement a communication specific child cookie. This cookie
- * can be used in the device communication interface by performing
- * a C++ dynamic cast and passing it to a child device handler, which stores
- * it and passes the Cookie to the communication interface where it can be used
- * by again performing a dynamic cast.
+ * To use this class, implement a communication specific child cookie which
+ * inherits Cookie. Cookie instances are created in config/ Factory.cpp by calling
+ * CookieIF* childCookie = new ChildCookie(...).´
+ *
+ * This cookie is then passed to the child device handlers, which stores the
+ * pointer and passes it to the communication interface functions.
+ *
  * The cookie can be used to store all kinds of information
  * about the communication, like slave addresses, communication status,
  * communication parameters etc.
