+ngtcp2
+======
+
+"Call it TCP/2.  One More Time."
+
+ngtcp2 project is an effort to implement `RFC9000
+<https://datatracker.ietf.org/doc/html/rfc9000>`_ QUIC protocol.
+
+Documentation
+-------------
+
+`Online documentation <https://nghttp2.org/ngtcp2/>`_ is available.
+
+Public test server
+------------------
+
+The following endpoints are available to try out ngtcp2
+implementation:
+
+- https://nghttp2.org:4433
+- https://nghttp2.org:4434 (requires address validation token)
+- https://nghttp2.org (powered by `nghttpx
+  <https://nghttp2.org/documentation/nghttpx.1.html>`_)
+
+  This endpoints sends Alt-Svc header field to clients if it is
+  accessed via HTTP/1.1 or HTTP/2 to tell them that HTTP/3 is
+  available at UDP 443.
+
+Requirements
+------------
+
+The libngtcp2 C library itself does not depend on any external
+libraries.  The example client, and server are written in C++20, and
+should compile with the modern C++ compilers (e.g., clang >= 11.0, or
+gcc >= 11.0).
+
+The following packages are required to configure the build system:
+
+- pkg-config >= 0.20
+- autoconf
+- automake
+- autotools-dev
+- libtool
+
+To build sources under the examples directory, libev and nghttp3 are
+required:
+
+- libev
+- `nghttp3 <https://github.com/ngtcp2/nghttp3>`_ for HTTP/3
+
+To enable `TLS Certificate Compression
+<https://datatracker.ietf.org/doc/html/rfc8879>`_ in bsslclient and
+bsslserver (BoringSSL (aws-lc) examples client and server), the
+following library is required:
+
+- libbrotli-dev >= 1.0.9
+
+ngtcp2 crypto helper library, and client and server under examples
+directory require at least one of the following TLS backends:
+
+- `quictls
+  <https://github.com/quictls/openssl/tree/OpenSSL_1_1_1w+quic>`_
+- GnuTLS >= 3.7.5
+- BoringSSL (commit 23018360710de333b3343e63cbb3bd2dceb3287d);
+  or aws-lc >= 1.39.0
+- Picotls (commit bbcdbe6dc31ec5d4b72a7beece4daf58098bad42)
+- wolfSSL >= 5.5.0
+- LibreSSL >= v3.9.2
+- OpenSSL >= 3.5.0 (experimental)

+
+Client/Server
+-------------
+
+After successful build, the client and server executable should be
+found under examples directory.  They talk HTTP/3.
+
+Client
+~~~~~~
+
+.. code-block:: shell
+
+   $ examples/wsslclient [OPTIONS] <HOST> <PORT> [<URI>...]
+
+The notable options are:
+
+- ``-d``, ``--data=<PATH>``: Read data from <PATH> and send it to a
+  peer.
+
+Server
+~~~~~~
+
+.. code-block:: shell
+
+   $ examples/wsslserver [OPTIONS] <ADDR> <PORT> <PRIVATE_KEY_FILE> <CERTIFICATE_FILE>
+
+The notable options are:
+
+- ``-V``, ``--validate-addr``: Enforce stateless address validation.
+
+H09wsslclient/H09wsslserver
+---------------------------
+
+There are h09wsslclient and h09wsslserver which speak HTTP/0.9.  They
+are written just for `quic-interop-runner
+<https://github.com/marten-seemann/quic-interop-runner>`_.  They share
+the basic functionalities with HTTP/3 client and server but have less
+functions (e.g., h09wsslclient does not have a capability to send
+request body, and h09wsslserver does not understand numeric request
+path, like /1000).
+
+Resumption and 0-RTT
+--------------------
+
+In order to resume a session, a session ticket, and a transport
+parameters must be fetched from server.  First, run
+examples/wsslclient with --session-file, and --tp-file options which
+specify a path to session ticket, and transport parameter files
+respectively to save them locally.
+
+Once these files are available, run examples/wsslclient with the same
+arguments again.  You will see that session is resumed in your log if
+resumption succeeds.  Resuming session makes server's first Handshake
+packet pretty small because it does not send its certificates.
+
+To send 0-RTT data, after making sure that resumption works, use -d
+option to specify a file which contains data to send.
+
+Token (Not something included in Retry packet)
+----------------------------------------------
+
+QUIC server might send a token to client after connection has been
+established.  Client can send this token in subsequent connection to
+the server.  Server verifies the token and if it succeeds, the address
+validation completes and lifts some restrictions on server which might
+speed up transfer.  In order to save and/or load a token,
+use --token-file option of examples/wsslclient.  The given file is
+overwritten if it already exists when storing a token.
+
+Crypto helper library
+---------------------
+
+In order to make TLS stack integration less painful, we provide a
+crypto helper library which offers the basic crypto operations.
+
+The header file exists under crypto/includes/ngtcp2 directory.
+
+Each library file is built for a particular TLS backend.  The
+available crypto helper libraries are:
+
+- libngtcp2_crypto_quictls: Use quictls and libressl as TLS backend
+- libngtcp2_crypto_gnutls: Use GnuTLS as TLS backend
+- libngtcp2_crypto_boringssl: Use BoringSSL and aws-lc as TLS backend
+- libngtcp2_crypto_picotls: Use Picotls as TLS backend
+- libngtcp2_crypto_wolfssl: Use wolfSSL as TLS backend
+- libngtcp2_crypto_ossl: Use OpenSSL as TLS backend (experimental)
+
+Because BoringSSL and Picotls are an unversioned product, we only
+tested their particular revision.  See Requirements section above.
+
+We use Picotls with OpenSSL as crypto backend.
+
+libngtcp2_crypto_ossl has some restrictions for its use because
+OpenSSL QUIC TLS API requires us to keep crypto data in tact until it
+says that they are no longer used.  It also requires us to keep
+transport parameter buffer.  This extra book keeping is just done for
+a couple of TLS messages exchanged during handshake and a couple of
+session tickets after handshake.  If you absolutely need to use
+OpenSSL backend, your application must make sure that:
+
+- Keep `ngtcp2_conn` alive until ``SSL`` object is freed by
+  ``SSL_free``; or
+- Call ``SSL_set_app_data(ssl, NULL)`` before calling ``SSL_free``
+
+If you cannot make sure neither of them, it is a good time to migrate
+your application to the other alternative (e.g., wolfSSL, aws-lc).
+
+libngtcp2_crypto_quictls and libngtcp2_crypto_ossl cannot be built at
+the same time.
+
+The examples directory contains client and server that are linked to
+those crypto helper libraries and TLS backends.  They are only built
+if their corresponding crypto helper library is built:
+
+- qtlsclient: quictls(libressl) client
+- qtlsserver: quictls(libressl) server
+- gtlsclient: GnuTLS client
+- gtlsserver: GnuTLS server
+- bsslclient: BoringSSL(aws-lc) client
+- bsslserver: BoringSSL(aws-lc) server
+- ptlsclient: Picotls client
+- ptlsserver: Picotls server
+- wsslclient: wolfSSL client
+- wsslserver: wolfSSL server
+- osslclient: OpenSSL client
+- osslserver: OpenSSL server
+
+QUIC protocol extensions
+-------------------------
+
+The library implements the following QUIC protocol extensions:
+
+- `An Unreliable Datagram Extension to QUIC
+  <https://datatracker.ietf.org/doc/html/rfc9221>`_
+- `Greasing the QUIC Bit
+  <https://datatracker.ietf.org/doc/html/rfc9287>`_
+- `Compatible Version Negotiation for QUIC
+  <https://datatracker.ietf.org/doc/html/rfc9368>`_
+- `QUIC Version 2
+  <https://datatracker.ietf.org/doc/html/rfc9369>`_
+
+Configuring Wireshark for QUIC
+------------------------------
+
+`Wireshark <https://www.wireshark.org/download.html>`_ can be configured to
+analyze QUIC traffic using the following steps:
+
+1. Set *SSLKEYLOGFILE* environment variable:
+
+   .. code-block:: shell
+
+      $ export SSLKEYLOGFILE=quic_keylog_file
+
+2. Set the port that QUIC uses
+
+   Go to *Preferences->Protocols->QUIC* and set the port the program
+   listens to.  In the case of the example application this would be
+   the port specified on the command line.
+
+3. Set Pre-Master-Secret logfile
+
+   Go to *Preferences->Protocols->TLS* and set the *Pre-Master-Secret
+   log file* to the same value that was specified for *SSLKEYLOGFILE*.
+
+4. Choose the correct network interface for capturing
+
+   Make sure you choose the correct network interface for
+   capturing. For example, if using localhost choose the *loopback*
+   network interface on macos.
+
+5. Create a filter
+
+   Create A filter for the udp.port and set the port to the port the
+   application is listening to. For example:
+
+   .. code-block:: text
+
+      udp.port == 7777
