+# Rocket
+
+[1-click deploy](https://portal.defang.dev/redirect?url=https%3A%2F%2Fgithub.com%2Fnew%3Ftemplate_name%3Dsample-rocket-template%26template_owner%3DDefangSamples)
+
+This sample demonstrates how to deploy a very simple Rocket app. Rocket is a web framework for Rust.
+
+## Prerequisites
+
+1. [!NOTE] Download [Defang CLI](https://github.com/DefangLabs/defang)
+2. (Optional) If you are using [Defang BYOC](https://docs.aws.amazon.com/cli/latest/userguide/cli-chap-configure.html) authenticate against your AWS account
+3. (Optional for local development) [Docker CLI](https://docs.docker.com/engine/install/)
+
+## Development
+
+To run the application locally, you can use the following command:
+
+```bash
+docker compose up
+```
+
+## Deployment
+
+> [!NOTE]
+> Download [Defang CLI](https://github.com/DefangLabs/defang)
+
+### Defang Playground
+
+Deploy your application to the defang playground by opening up your terminal and typing `defang up`.
+
+### BYOC (AWS)
+
+If you want to deploy to your own cloud account, you can use Defang BYOC:
+
+1. [Authenticate your AWS account](https://docs.aws.amazon.com/cli/latest/userguide/cli-chap-configure.html), and that you have properly set your environment variables like `AWS_PROFILE`, `AWS_REGION`, `AWS_ACCESS_KEY_ID`, and `AWS_SECRET_ACCESS_KEY`.
+2. Run `defang up` in a terminal that has access to your AWS environment variables.
