+# Examples - Invocation
+
+This example demonstrates how to use the Invocation API.
+
+## Run
+
+```bash
+# If it is not already, initialize DAPR on the system
+dapr init
+
+# Install dependenies
+npm install
+
+# Run the example
+npm run start:dapr-http
+```
+
+## Switching to gRPC
+
+By default the example will run using HTTP. To use gRPC, do the following:
+* Replace both occurences of `process.env.DAPR_HTTP_PORT` with `process.env.DAPR_GRPC_PORT`
+* Replace both occurences of `CommunicationProtocolEnum.HTTP` with `CommunicationProtocolEnum.GRPC`
+* Instead of `npm run start:dapr-http` run `npm run start:dapr-grpc`
