Code Review

This pull request introduces a minor textual change in the README.md file to improve clarity regarding telemetry opt-out. While the change is a step in the right direction, I've provided a suggestion to make the phrasing more concise and direct for better readability. Overall, it's a good small improvement to the documentation.
