Other than the the OpenShift console workflow and "Customizing the Istio configuration" section of the README, we do not document our operator design.

Some things to include...

• How to specify the version of Istio to install (Master - the current WIP Istio release); How to know what versions are available; A recommendation of what version to use.
  • A note on the anyuid workaround (version considerations - 1.19.3 needs workaround, 1.20+ does not) - " For versions 1.19.x and earlier, ...."
  • profile config - is there anything we want to say here?
• Istioctl instructions (before "Intalling the Bookinfo application" section) - install the utility using the version selected earlier (using https://istio.io/downloadIstioctl)
  • See: https://docs.google.com/document/d/1eL7wFLUAOnPNpYMOKd3NVlLhLHEHuh4b1QkroGgV3Tc/edit#heading=h.vwx3nefbjbl
• An example Istio config, showing the version and values field under the "Customizing Istio configuration" section.
  • Add a description of the `rawValues` field and when it should be used.
• What is available from - https://issues.redhat.com/browse/OSSM-4050
• Other operator design considerations to note?

This doesn't need to be polished - similar to an internal wiki, but we want to make sure the operator design thinking gets captured while it is fresh. This will also help us get more feedback from the Istio community when we push it upstream.
