+To build h2load and nghttpx with HTTP/3 feature enabled, run the
+configure script with ``--enable-http3``.
+
+For nghttpx to reload configurations and swapping its executable while
+gracefully terminating old worker processes, eBPF is required.  Run
+the configure script with ``--enable-http3 --with-libbpf`` to build

+``--frontend-quic-secret-file`` in order to keep the existing
+connections alive during reload.

+Stream priorities
+-----------------
+
+By default, the stream prioritization scheme described in :rfc:`7540`
+is used.  This scheme has been formally deprecated by :rfc:`9113`.  In
+order to disable it, send
+:enum:`nghttp2_settings_id.NGHTTP2_SETTINGS_NO_RFC7540_PRIORITIES` of
+value of 1 via `nghttp2_submit_settings()`.  This settings ID is
+defined by :rfc:`9218`.  The sender of this settings value disables
+RFC 7540 priorities, and instead it enables RFC 9218 Extensible
+Prioritization Scheme.  This new prioritization scheme has 2 methods
+to convey the stream priorities to a remote endpoint: Priority header
+field and PRIORITY_UPDATE frame.  nghttp2 supports both methods.  In
+order to receive and process PRIORITY_UPDATE frame, server has to call
+``nghttp2_option_set_builtin_recv_extension_type(option,
+NGHTTP2_PRIORITY_UPDATE)`` (see the above section), and pass the
+option to `nghttp2_session_server_new2()` or
+`nghttp2_session_server_new3()` to create a server session.  Client
+can send Priority header field via `nghttp2_submit_request()`.  It can
+also send PRIORITY_UPDATE frame via
+`nghttp2_submit_priority_update()`.  Server processes Priority header
+field in a request header field and updates the stream priority unless
+HTTP messaging rule enforcement is disabled (see
+`nghttp2_option_set_no_http_messaging()`).
+
+For the purpose of smooth migration from RFC 7540 priorities, client
+is advised to send
+:enum:`nghttp2_settings_id.NGHTTP2_SETTINGS_NO_RFC7540_PRIORITIES` of
+value of 1.  Until it receives the first server SETTINGS frame, it can
+send both RFC 7540 and RFC 9128 priority signals.  If client receives
+SETTINGS_NO_RFC7540_PRIORITIES of value of 0, or it is omitted ,
+client stops sending PRIORITY_UPDATE frame.  Priority header field
+will be sent in anyway since it is an end-to-end signal.  If
+SETTINGS_NO_RFC7540_PRIORITIES of value of 1 is received, client stops
+sending RFC 7540 priority signals.  This is the advice described in
+:rfc:`9218#section-2.1.1`.
+
+Server has an optional mechanism to fallback to RFC 7540 priorities.
+By default, if server sends SETTINGS_NO_RFC7540_PRIORITIES of value of
+1, it completely disables RFC 7540 priorities and no fallback.  By
+setting nonzero value to
+`nghttp2_option_set_server_fallback_rfc7540_priorities()`, server
+falls back to RFC 7540 priorities if it sends
+SETTINGS_NO_RFC7540_PRIORITIES value of value of 1, and client omits
+SETTINGS_NO_RFC7540_PRIORITIES in its SETTINGS frame.

 connections.  This feature is enabled by default and no configuration
 is required.
 
+WebSockets over HTTP/3 is also supported.
+
+HTTP/3
+------
+
+nghttpx supports HTTP/3 if it is built with HTTP/3 support enabled.
+HTTP/3 support is experimental.
+
+In order to listen UDP port to receive HTTP/3 traffic,
+:option:`--frontend` option must have ``quic`` parameter:
+
+.. code-block:: text
+
+   frontend=*,443;quic
+
+The above example makes nghttpx receive HTTP/3 traffic on UDP
+port 443.
+
+nghttpx does not support HTTP/3 on backend connection.
+
+Hot swapping (SIGUSR2) or configuration reload (SIGHUP) require eBPF
+program.  Without eBPF, old worker processes keep getting HTTP/3
+traffic and do not work as intended.  The QUIC keying material to
+encrypt Connection ID must be set with
+:option:`--frontend-quic-secret-file` and must provide the existing
+keys in order to keep the existing connections alive during reload.
+
+The construction of Connection ID closely follows Block Cipher CID
+Algorithm described in `QUIC-LB draft
+<https://datatracker.ietf.org/doc/html/draft-ietf-quic-load-balancers>`_.
+A Connection ID that nghttpx generates is always 20 bytes long.  It
+uses first 2 bits as a configuration ID.  The remaining bits in the
+first byte are reserved and random.  The next 4 bytes are server ID.
+The next 4 bytes are used to route UDP datagram to a correct
+``SO_REUSEPORT`` socket.  The remaining bytes are randomly generated.
+The server ID and the next 12 bytes are encrypted with AES-ECB.  The
+key is derived from the keying materials stored in a file specified by
+:option:`--frontend-quic-secret-file`.  The first 2 bits of keying
+material in the file is used as a configuration ID.  The remaining
+bits and following 3 bytes are reserved and unused.  The next 32 bytes
+are used as an initial secret.  The remaining 32 bytes are used as a
+salt.  The encryption key is generated by `HKDF
+<https://datatracker.ietf.org/doc/html/rfc5869>`_ with SHA256 and
+these keying materials and ``connection id encryption key`` as info.
+
+In order announce that HTTP/3 endpoint is available, you should
+specify alt-svc header field.  For example, the following options send
+alt-svc header field in HTTP/1.1 and HTTP/2 response:
+
+.. code-block:: text
+
+   altsvc=h3,443,,,ma=3600
+   http2-altsvc=h3,443,,,ma=3600

+==========
+
+Dockerfile creates the applications bundled with nghttp2.
+These applications are:
+
+- nghttp
+- nghttpd
+- nghttpx
+- h2load
+
+HTTP/3 and eBPF features are enabled.
+
+In order to run nghttpx with HTTP/3 endpoint, you need to run the
+image with the escalated privilege.  Here is the example command-line
+to run nghttpx to listen to HTTP/3 on port 443, assuming that the
+current directory contains a private key and a certificate in
+server.key and server.crt respectively:
+
+.. code-block:: text
+
+   $ docker run --rm -it -v /path/to/certs:/shared --net=host --privileged \
