  * @brief	The LocalDataSet class manages a set of locally checked out
  *          variables for local data pools
  * @details
+ * Extends the PoolDataSetBase class for local data pools by introducing
+ * a validity state, a flag to mark the set as changed, and various other
+ * functions to make it usable by the LocalDataPoolManager class.
+ *
  * This class manages a list, where a set of local variables (or pool variables)
  * are registered. They are checked-out (i.e. their values are looked
  * up and copied) with the read call. After the user finishes working with the
  * pool variables, he can write back all variable values to the pool with
- * the commit call. The data set manages locking and freeing the local data pools,
- * to ensure thread-safety.

+ * pools, to ensure thread-safety.
+ *
+ * Pool variables can be added to the dataset by using the constructor
+ * argument of the pool variable or using the #registerVariable member function.
  *
  * An internal state manages usage of this class. Variables may only be
- * registered before the read call is made, and the commit call only
+ * registered before any read call is made, and the commit call can only happen
  * after the read call.
