+
+## Running the sample
+
+1. Open the script DemonstrateDDM.sql in Management Studio and connect to the WideWorldImporters database.
+
+2. Follow the instructions in the script.
+
+## Sample details
+
+The WideWorldImporters sample database leverages Dynamic Data Masking to mask sensitive banking data in the table 'Purchasing.Suppliers'.
+
+When connecting to the database and running a query using a privileged user such as the database owner, you will see the sensitive data in the clear.
+
+The user 'GreatLakesSales' is an example unprivileged user, and will only see the masked values.
