 # Connecting with a DataSource
-In addition to the `DriverManager` class, one can also use a datasource to establish new connections.
-The JDBC Wrapper has a built-in datasource class called [AwsWrapperDataSource](../../wrapper/src/main/java/com/amazon/awslabs/jdbc/ds/AwsWrapperDataSource.java).
-The `AwsWrapperDataSource` enables the JDBC Wrapper to work with various driver-specific datasources.
+You can use the `DriverManager` class or a datasource to establish a new connection when using the JDBC Wrapper. The JDBC Wrapper has a built-in datasource class named [AwsWrapperDataSource](../../wrapper/src/main/java/com/amazon/awslabs/jdbc/ds/AwsWrapperDataSource.java) that allows the JDBC Wrapper to work with various driver-specific datasources.

 ### Configurable DataSource Properties
