We need to add some more information about the CLI, what the purpose is, what the key features are and how we can download + install it.

Extra points: additional information on defining the schema would be useful, also more examples to explain along.

You can get inspired to what ODO has: https://github.com/openshift/odo#odo---developer-focused-cli-for-kubernetes-and-openshift

AC:

• README.md should cover key features, purpose and functionality we support and how to configure it along with examples
• README.md should cover steps to download and install binaries (pending on CFE-97)
