After removing the GitHub discussions contact information, line 11 states "Support for this PROJECT is limited to the resources listed above." However, the only resource now listed is GitHub Issues for bugs and feature requests. This creates a gap for users who need help or have questions (not bugs/feature requests). Consider either:

1. Updating line 11 to clarify that only bug reports and feature requests are supported via GitHub Issues, or
2. Adding an alternative resource for help and questions (such as the email contact found in CONTRIBUTING.md: AziHSM_OSS@Microsoft.com), or
3. Explicitly stating that help and questions are not supported if that is the intention.
