@avoguru can you please confirm that this PR works in your environment?

[avoguru]

This version change works. Docs needs improvement, the installation process needs more clarity (raised a internal jira for the same - DEVX-2677)

[ybyzek]

@avoguru can you please elaborate on improvement needed in the installation process? The source doc lives in this repo, so it could optionally be fixed in this PR as well.
