+nghttp3
+=======
+
+nghttp3 is an implementation of `RFC 9114
+<https://datatracker.ietf.org/doc/html/rfc9114>`_ HTTP/3 mapping over
+QUIC and `RFC 9204 <https://datatracker.ietf.org/doc/html/rfc9204>`_
+QPACK in C.
+
+It does not depend on any particular QUIC transport implementation.
+
+Documentation
+-------------
+
+`Online documentation <https://nghttp2.org/nghttp3/>`_ is available.
+
+Build from git
+---------------
+
+.. code-block:: shell
+
+   $ git clone https://github.com/ngtcp2/nghttp3
+   $ cd nghttp3
+   $ git submodule update --init
+   $ autoreconf -i
+   $ ./configure
+   $ make -j$(nproc) check
+
+HTTP/3
+------
+
+This library implements `RFC 9114
+<https://datatracker.ietf.org/doc/html/rfc9114>`_ HTTP/3.  It does not
+support server push.
+
+The following extensions have been implemented:
+
+- `Extensible Prioritization Scheme for HTTP
+  <https://datatracker.ietf.org/doc/html/rfc9218>`_
+- `Bootstrapping WebSockets with HTTP/3
+  <https://datatracker.ietf.org/doc/html/rfc9220>`_
+
+It can also send and receive `SETTINGS_H3_DATAGRAM` from `HTTP
+Datagrams and the Capsule Protocol
+<https://datatracker.ietf.org/doc/html/rfc9297>`_.
+
+QPACK
+-----
+
+This library implements `RFC 9204
+<https://datatracker.ietf.org/doc/html/rfc9204>`_ QPACK.  It supports
+dynamic table.
+
+Optimizations
+-------------
+
+This library optionally uses AVX2, if available, to optimize its
+performance.  To compile with AVX2, add ``-mavx2`` to CFLAGS.  Note
+that by default, CFLAGS is set to ``-g -O2``.  When specifying CFLAGS,
+include them as well (e.g., ``-g -O2 -mavx2``).
