+This is an example of how to use the grpc middleware.
+
+# Using it
+
+To try this out:
+
+* Install all dependencies with `go mod vendor`.
+* Run `go run main.go` to start the app.
+* Use [jwt.io](https://jwt.io/) to generate a JWT signed with the HS256 algorithm and `abcdefghijklmnopqrstuvwxyz012345`.
+* [optional] use [grpc-client-cli](https://github.com/vadimi/grpc-client-cli) and run `echo '{"msg":"hello"}' | grpc-client-cli --insecure --proto=example.proto --header "authorization: <jwt from jwt.io>" --service ExampleService --method DoSomething localhost:8080
