-# Overview
-
-Describe the intended usage of this charm and anything unique about how this
-charm relates to others here.
-
-This README will be displayed in the Charm Store, it should be either Markdown
-or RST. Ideal READMEs include instructions on how to use the charm, expected
-usage, and charm features that your audience might be interested in. For an
-example of a well written README check out Hadoop:
-http://jujucharms.com/charms/precise/hadoop
-
-Use this as a Markdown reference if you need help with the formatting of this
-README: http://askubuntu.com/editing-help
-
-This charm provides [service][]. Add a description here of what the service
-itself actually does.
-
-Also remember to check the [icon guidelines][] so that your charm looks good
-in the Juju GUI.
-
-# Usage
-
-Step by step instructions on using the charm:
-
-juju deploy servicename
-
-and so on. If you're providing a web service or something that the end user
-needs to go to, tell them here, especially if you're deploying a service that
-might listen to a non-default port.
-
-You can then browse to http://ip-address to configure the service.
-
-## Scale out Usage
-
-If the charm has any recommendations for running at scale, outline them in
-examples here. For example if you have a memcached relation that improves
-performance, mention it here.
-
-## Known Limitations and Issues
-
-This not only helps users but gives people a place to start if they want to help
-you add features to your charm.
-
-# Configuration
-
-The configuration options will be listed on the charm store, however If you're
-making assumptions or opinionated decisions in the charm (like setting a default
-administrator password), you should detail that here so the user knows how to
-change it immediately, etc.
-
-# Contact Information
-
-Though this will be listed in the charm store itself don't assume a user will
-know that, so include that information here:
-
-## Upstream Project Name
-
-  - Upstream website
-  - Upstream bug tracker
-  - Upstream mailing list or contact information
-  - Feel free to add things if it's useful for users
