+# Podman Desktop OpenShift Developer Sandbox Extension
 
-# Build Installation
+This extension puts you to just few clicks away form deploying your application to [OpenShift Developer Sandbox](https://developers.redhat.com/developer-sandbox), a 30 days no cost shared cluster on [OpenShift](https://www.redhat.com/en/technologies/cloud-computing/openshift).
+After few simple configuration steps the extension allows you to push an image to Sandbox internal image registry, so you can create and start containers from that image in OpenShift cluster using Podman Desktop UI.
