+The associated proto files are located at `Sources/Examples/v1/HelloWorld/Model/helloworld.proto`, and
+`Sources/Examples/v1/Echo/Model/echo.proto` respectively.
 
 In order to generate the reflection data for the `helloworld.proto`, you can run the following command:
 
 ```sh
-$ protoc Sources/Examples/HelloWorld/Model/helloworld.proto \
-    --proto_path=Sources/Examples/HelloWorld/Model \
+$ protoc Sources/Examples/v1/HelloWorld/Model/helloworld.proto \
+    --proto_path=Sources/Examples/v1/HelloWorld/Model \

-    --grpc-swift_out=Sources/Examples/ReflectionService/Generated
+    --grpc-swift_out=Sources/Examples/v1/ReflectionService/Generated
 ```
 
 Let's break the command down:
 - The first argument passed to `protoc` is the path
   to the `.proto` file to generate reflection data
-  for: [`Sources/Examples/HelloWorld/Model/helloworld.proto`][helloworld-proto].
-- The `proto_path` flag is the path to search for imports: `Sources/Examples/HelloWorld/Model`.
+  for: [`Sources/Examples/v1/HelloWorld/Model/helloworld.proto`][helloworld-proto].
+- The `proto_path` flag is the path to search for imports: `Sources/Examples/v1/HelloWorld/Model`.
 - The 'grpc-swift_opt' flag allows us to list options for the Swift generator.
   To generate only the reflection data set: `Client=false,Server=false,ReflectionData=true`.
 - The `grpc-swift_out` flag is used to set the path of the directory
-  where the generated file will be located: `Sources/Examples/ReflectionService/Generated`.
+  where the generated file will be located: `Sources/Examples/v1/ReflectionService/Generated`.
 
 This command assumes that the `protoc-gen-grpc-swift` plugin is in your `$PATH` environment variable.
 You can learn how to get the plugin from this section of the `grpc-swift` README:
