+# Overview
+
+This charm provides a blank [Ubuntu](http://ubuntu.com) image. It does not provide any services other than a blank cloud image for you to manage manually, it is intended for testing and development. 
+
+# Usage
+
+Step by step instructions on using this charm:
+
+    juju deploy ubuntu
+
+You can then ssh to the instance with:
+
+    juju ssh ubuntu/0
+
+## Scale out Usage
+
+This charm is not designed to be used at scale since it does not have any relationships, however you can bulk add machines with `add-unit`:
+
+    juju add-unit ubuntu      # Add one more
+    juju add-unit -n5 ubuntu  # Add 5 at a time
+
+
+You can also alias names in order to organize a bunch of empty instances:
+
+    juju deploy ubuntu mytestmachine1
+    juju deploy ubuntu mytestmachine2
+
+and so on. 
+
+## Known Limitations and Issues
+
+This charm does not provide anything other than a blank server, so it does not relate to other charms.
+
+# Configuration
+
+This charm has no configuration options.
