+
+## Documentation Gaps to Fill
+
+Based on the audit, the following documentation gaps have been identified:
+
+1. **Formal Changelog**: The `changelog` directory should be repurposed to maintain a formal changelog, documenting all changes, new features, and bug fixes for each release.
+
+2. **User Guide**: A comprehensive user guide should be created to provide end-users with a clear understanding of the framework's features and how to use them.
+
+3. **External Documentation**: The external documentation at `https-core-help` is inaccessible and should be reviewed to ensure it is up-to-date and publicly available.
+
+4. **Architecture Diagram**: A visual representation of the system's architecture would be beneficial for new contributors and users.
+
+5. **ADRs**: The project should adopt Architecture Decision Records (ADRs) to document key architectural decisions and their rationale.
