 **Notes**
 
 - Import the `Workbook` object from the `tableaudocumentapi` module.
 - To open a workbook, instantiate a `Workbook` object and pass the `.twb` file name in the constructor.
 - The `Workbook` object exposes a `datasources` collection.
-- Each datasource object has a `connection` object that supports a `server`, `dbname`, and `username` property. 
-- Save changes to the workbook by calling the `save` or `save_as` method.    
+- Each datasource object has a `connection` object that supports a `server`, `dbname`, and `username` property.
+- Save changes to the workbook by calling the `save` or `save_as` method.
 
 
 
 ###Examples
 
-The downloadable package contains an example named `replicateWorkbook.py` (in the folder `\Examples\Replicate Workbook`). This example reads an existing workbook and reads a .csv file that contains a list of servers, database names, and users. For each new user in the .csv file, the code copies the original workbook, updates the `server`, `dbname`, and `username` properties, and saves the workbook under a new name.
