Binaries integrated into the User Journey and readme.md

Issue Once we have working binaries we need to update our user-facing documentation to clarify the install flow.

Importance If we don't tell users how to access the new features or integrate them into our user journey they won't benefit from the changes.

Definition of Done Update our install documentation and install tooling to leverage these binaries.
