 This Node.js application, built with Express.js, is designed to inspect and display detailed information about incoming HTTP requests. It supports all HTTP methods and provides insights into the request path, method, headers, query parameters, and body. Note alongside your project, you should also include a package.json file that includes the relevant metadata such as package dependencies, scripts, project verrsions so that the Dockerfile can install necessary dependencies.
 
-## Essential Setup Files
+## Prerequisites
 
-1. A [Dockerfile](https://docs.docker.com/develop/develop-images/dockerfile_best-practices/).
-2. A [compose file](https://docs.defang.io/docs/concepts/compose) to define and run multi-container Docker applications (this is how Defang identifies services to be deployed).
+1. Download [Defang CLI](https://github.com/DefangLabs/defang)
+2. (Optional) If you are using [Defang BYOC](https://docs.defang.io/docs/concepts/defang-byoc) authenticate with your cloud provider account
+3. (Optional for local development) [Docker CLI](https://docs.docker.com/engine/install/)
 
-## Prerequisite
+## Development
 
-1. Download [Defang CLI](https://github.com/DefangLabs/defang)
-2. If you are using [Defang BYOC](https://docs.defang.io/docs/concepts/defang-byoc), make sure you have properly [authenticated your AWS account (optional)](https://docs.aws.amazon.com/cli/latest/userguide/cli-chap-configure.html)
+To run the application locally, you can use the following command:
+
+```bash
+docker compose up --build
+```
+
+## Configuration
+
+For this sample, you will not need to provide [configuration](https://docs.defang.io/docs/concepts/configuration). 
+
+If you wish to provide configuration, see below for an example of setting a configuration for a value named `API_KEY`.
+
+```bash
+defang config set API_KEY
+```
+

+
+### Defang Playground
+
+Deploy your application to the Defang Playground by opening up your terminal and typing:
+```bash
+defang compose up
+```
+
+### BYOC (AWS)
 
-## A Step-by-Step Guide
+If you want to deploy to your own cloud account, you can [use Defang BYOC](https://docs.defang.io/docs/tutorials/deploy-to-your-cloud).
 
-1. Open the terminal and type `defang login`
-2. Type `defang compose up` in the CLI
-3. Your app should be up and running with Defang in minutes!
