 The dockerized version of the playground comes with the same set of examples as the [online version](https://eclipse.org/epsilon/playground). To start an instance with your own examples on the left hand side, use the following command, replacing `<examples-folder-absolute-path>` with the **absolute** path of your `examples` folder.
 
 ```shell
-docker run -p 8000:80 -v <examples-folder-absolute-path>:/etc/nginx/html/examples playground:latest
+docker run -p 8000:80 -v <examples-folder-absolute-path>:/etc/nginx/html/examples playground-docker:micronaut
 ```
 
 Your `examples` folder should contain an `examples.json` file with at least one example. A sample `examples` folder with a single example is provided [in this repository](examples) and more examples are available in the `examples` folder of [Epsilon's website repository](https://github.com/eclipse-epsilon/epsilon-website/tree/main/mkdocs/docs/playground/examples).

 If you would like to use only the backend services and replace the front-end altogether, you can start an instance using the following command, replacing `<front-end-folder-absolute-path>` with the **absolute** path of your custom front-end folder.
 
 ```shell
-docker run -p 8000:80 -v <front-end-folder-absolute-path>:/etc/nginx/html playground:latest
+docker run -p 8000:80 -v <front-end-folder-absolute-path>:/etc/nginx/html playground-docker:micronaut
 ```
 Your front-end folder should contain an `index.html` file. A minimal alternative front-end that you can use as a starting point for developing your custom front-end is available in the `miniground` folder of [this repository](miniground).
 
 Alternatively, you may want to use the [Docker image for the Micronaut-based backend](https://github.com/epsilonlabs/playground-micronaut/pkgs/container/playground-micronaut) directly, without using this image.

-Run the following command to build a `linux/amd64` image (replace `x.y.z` with the actual version you wish to release)
-
-```
-docker buildx build --no-cache --platform linux/amd64 -t eclipseepsilon/playground:x.y.z .
-docker tag eclipseepsilon/playground:x.y.z eclipseepsilon/playground:latest
