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

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

change it immediately, etc.
