+By default, we will use `APIGatewayRestResolver` throughout the documentation. You can use any of the following:
 
-For resolvers, we provide: `APIGatewayRestResolver`, `APIGatewayHttpResolver`, `ALBResolver`, `LambdaFunctionUrlResolver`, and `VPCLatticeResolver`. From here on, we will default to `APIGatewayRestResolver` across examples.
