 ##### Saving and loading a configuration
 Instances of your configuration class have a `load`, `save` and `loadAndSave` method:
-- `save` dumps all fields which are not `final`, `static` or `transient` to a configuration file.
-  If the file exists, it is overridden; otherwise, it is created.
-- `load` reads the configuration file and updates the instance's field values.
-- `loadAndSave` loads the configuration file and then calls `save` to update the file.
-If the file doesn't exist, it is saved.
+- `load` reads the configuration file and updates the field values of your instance.
+- `save` dumps all field names and values to a configuration file. If the file exists, it is 
+overridden; otherwise, it is created.
+- `loadAndSave` first calls `load` and then `save`, which is useful when you have added or 
+removed fields from the class or you simply don't know if the configuration file exists.
