 ## Usage Instructions
 
-If the server/client depends on the API module with the `grpc-starter-validation` module, by default, both the server and client will automatically enable the validation feature. Before sending a request, the client will validate the request parameters, and upon receiving a request, the server will also validate the request parameters.
