-## API Documentation
+## Reference Manual
 
-The API documentation is provided in Asciidoc format in the
-`docs/man` subdirectory, and also
-[online](https://nng.nanomsg.org/man).
+The API documentation is currently in transition, as we are converting it from
+Asciidoc to `mdbook`. Most of the content has now been converted, and you can
+see it at [here](https://nng.nanomsg.org/ref). Part of the conversion includes
+a substantial reorganization for improved usability, with major content revisions
+and additions for NNG 2.0.
 
-> [!NOTE]
-> However, an effort to convert the documentation to Markdown using `mdbook`
-> is underway. You can see a preview it [here](https://nng.nanomsg.org/ref).

-The [_nng_(7)](docs/man/nng.7.adoc) page provides a conceptual overview and links to
-manuals for various patterns.
-The [_libnng_(3)](docs/man/libnng.3.adoc) page is a good starting point for the API reference.
+The remaining Asciidoc format documentation is in the `docs/man` subdirectory, and also
+[online](https://nng.nanomsg.org/man). It will eventually all be converted before 2.0
+is fully released.
