 The Lambda function is a C# application using .NET Core 2.1 (a similar approach works for any other language supported by
-AWS Lambda). To deploy the complete application:
-

-# Create and configure a new stack
-$ pulumi stack init testing
-$ pulumi config set aws:region us-east-2
-
-# Install dependencies
-$ npm install

-# Build the C# app

+## Deploying and running the Pulumi App
+
+1. Create a new stack:
+
+ ```bash
+ $ pulumi stack init dev
+ ```
+
+1. Restore NPM modules via `npm install` or `yarn install`.
+
+1. Build the C# application.
+
+ ```bash
+ dotnet publish app
+ ```
+
+1. Set the AWS region:
+
+ ```bash
+ $ pulumi config set aws:region us-east-2
+ ```
+
+1. Optionally, set AWS Lambda provisioned concurrency:
+
+ ```bash
+ $ pulumi config set provisionedConcurrency 1
+ ```
+
+1. Run `pulumi up` to preview and deploy changes:
+
+ ```
+ $ pulumi up
+ Previewing update (dev):
+ ...
+
+ Updating (dev):
+ ...
+ Resources:
+ + 10 created
+ Duration: 1m 20s
+ ```
+
+1. Check the deployed GraphQL endpoint:
+
+ ```
+ $ curl $(pulumi stack output endpoint)/hello
+ {"Path":"/hello","Count":0}
+ ```
+
+1. See the logs
+
+ ```
+ $ pulumi logs -f

+## Clean up
+
+1. Run `pulumi destroy` to tear down all resources.
+
+1. To delete the stack itself, run `pulumi stack rm`. Note that this command deletes all deployment history from the Pulumi Console.
