+# NGINX hello world
+
+This demonstrates a simple example of running the [NGINX base image](https://hub.docker.com/_/nginx/) on [Scaleway Serverless Containers](https://www.scaleway.com/en/serverless-containers/).
+
+## Requirements
+
+This example assumes you are familiar with how serverless containers work. If needed, you can
+check the [Scaleway official documentation](https://www.scaleway.com/en/docs/serverless/containers/quickstart/).
+
+This example uses the Scaleway Serverless Framework Plugin. Please set up your environment with the requirements stated in the [Scaleway Serverless Framework Plugin](https://github.com/scaleway/serverless-scaleway-functions) before trying out the example.
+
+## Deployment
+
+Once your environment is set up, you can deploy your container with:
+
+```sh
+npm install
+
+serverless deploy
+```
+
+When the deployment is complete, you should be able to `curl` the container's endpoint or hit it from a browser and see the NGINX default page.
+
+## Customising your deployment
+
+To serve custom resource from your NGINX container, you will need to:
+
+- Build a custom image containing these files
+- Push this image to a publicly accessible repo, or a private Scaleway container repo
+- Update the `registryImage` field in the `serverless.yml` file to point to your image, and redeploy
