 The [Hello Universe](https://github.com/spectrocloud/hello-universe) app includes an [API server](https://github.com/spectrocloud/hello-universe-api) that relies on a Postgres database for storing the number of clicks and other metadata about the clicks such as the browser, os, and timestamp. For your convenience, a Postgres container is available for use.
 
+## Prerequisites
+
+Ensure [Docker Desktop](https://www.docker.com/products/docker-desktop/) is available on your local machine. 
+
+- Use the following command and ensure you receive an output displaying the version number.
+    ```
+    docker version
+    ```
+    
+Alternatively, you can install [Podman](https://podman.io/docs/installation).
+
+- If you are not using a Linux operating system, create and start the Podman Machine in your local environment. Otherwise, skip this step.
+    ```
+    podman machine init
+    podman machine start
+    ```
+- Use the following command and ensure you receive an output displaying the installation information.
+    ```
+    podman info
+    ```
+
 ## Usage
 
-To get use the container you can issue the following command to download the container.
+You can issue the following commands to use the container with Docker.

+```
+docker pull ghcr.io/spectrocloud/hello-universe-db:1.1.0 && \
+docker run -p 5432:5432 ghcr.io/spectrocloud/hello-universe-db:1.1.0
+```
+
+If you choose Podman, you can use the following commands.
 
 ```
-docker pull ghcr.io/spectrocloud/hello-universe-db:1.0.2 && \
-docker run -p 5432:5432 ghcr.io/spectrocloud/hello-universe-db:1.0.2

+podman run -p 5432:5432 ghcr.io/spectrocloud/hello-universe-db:1.1.0
 ```
 
 The command you issued downloaded the container and exposed port `5432`. The default user name is `postgres` and the password is `password`.
