 ## Prerequisites
 > 📝 As long as Restate hasn't been launched publicly, you need to have access to the private Restate npm packages and Docker container. Please follow the instructions in the [restate-dist](https://github.com/restatedev/restate-dist) Readme to set up access: 
 
-- [NodeJS (and npm)](https://nodejs.org) installed.
+- [NodeJS (and npm)](https://nodejs.org)
 - [Docker Engine](https://docs.docker.com/engine/install/) or [Podman](https://podman.io/docs/installation) to launch the Restate runtime (not needed for the app implementation itself).
 - [curl](https://everything.curl.dev/get)
 - An AWS account with permissions for Lambda and API Gateway.

+This method increases a counter that is keyed by the name in the request. Send some subsequent requests for different names and watch the counters incrementing.

+:::tip
+The counters are stored in Restate. Restate supplies the state together with the request when it invokes the Lambda function.
+So your Lambda function does not need to worry about setting up connections to session databases etc.
+This makes the code easier and the execution faster.

 ## 🏁 You did it!
 You successfully added a Lambda function as a Restate service and sent requests to it.
 
 Here are some next steps for you to try:
-- Try to add a new method to the greeter function and redeploy the Lambda function with the new methods enabled.
+- Add a new method to the greeter function and redeploy the Lambda function with the new methods enabled.
 - Create and deploy a new Lambda function that calls the greeter function.
