 ## Options
-- `createdProperty` **string|false** Determines the name of the property use to store the created timestamp (default `"created_at"`). If set to `false`, disables this property.
-- `modifiedProperty` **string|false** Determines the name of the property used to store the modified timestamp (default `"modified_at"`). If set to `false`, disables this property.
-- `dbtype` **object** Allows you to set the type of column used by the DB to allow for custom data types (default `{ type: 'date', time: true }`)
-- `now` **function** Allows you to specify a custom function used to set the current time data for the database (default `function() { return new Date(); }`)
+- `createdProperty` **string|false** 
+  Determines the name of the property use to store the created timestamp (default `"created_at"`). If set to `false`, disables this property.
+- `modifiedProperty` **string|false** 
+  Determines the name of the property used to store the modified timestamp (default `"modified_at"`). If set to `false`, disables this property.
+- `dbtype` **object** 
+  Allows you to set the type of column used by the DB to allow for custom data types (default `{ type: 'date', time: true }`).
+- `now` **function**
+  Allows you to specify a custom function used to set the current time data for the database (default `function() { return new Date(); }`).
+- `persist` **boolean**
+  Used to prevent creation and modification timestamps from being stored in the database (default `true`).
 
 ## Features
 - Easy to add created and modified date/time information to your models
 - Highly customizable
 - Supports existing beforeCreate/beforeSave hooks through the use of a robust wrapper function
+- Allows values to be stored "in-memory" if usage scenarios don't require them to be stored in the database.
