creating a [bug or feature request](../BUGS-AND-FEATURE-REQUESTS.md),
or just coming to the weekly [Environments Working Group](https://github.com/istio/community/blob/master/WORKING-GROUPS.md)
meeting to share your ideas.

This document is an overview of how the operator works from a user perspective. For more details about the design and
