+libnghttp2_asio: High level HTTP/2 C++ library
+----------------------------------------------
+
+libnghttp2_asio is C++ library built on top of libnghttp2 and provides
+high level abstraction API to build HTTP/2 applications.  It depends
+on the Boost::ASIO library and OpenSSL.  Currently libnghttp2_asio
+provides both client and server APIs.
+
+libnghttp2_asio is not built by default.  Use the ``--enable-asio-lib``
+configure flag to build libnghttp2_asio.  The required Boost libraries
+are:
+
+* Boost::Asio
+* Boost::System
+* Boost::Thread
+
+The server API is designed to build an HTTP/2 server very easily to utilize
+C++14 anonymous functions and closures.  The bare minimum example of
+an HTTP/2 server looks like this:
+
+.. code-block:: cpp
+
+    #include <iostream>
+
+    #include <nghttp2/asio_http2_server.h>
+
+    using namespace nghttp2::asio_http2;
+    using namespace nghttp2::asio_http2::server;
+
+    int main(int argc, char *argv[]) {
+      boost::system::error_code ec;
+      http2 server;
+
+      server.handle("/", [](const request &req, const response &res) {
+        res.write_head(200);
+        res.end("hello, world\n");
+      });
+
+      if (server.listen_and_serve(ec, "localhost", "3000")) {
+        std::cerr << "error: " << ec.message() << std::endl;
+      }
+    }
+
+Here is sample code to use the client API:
+
+.. code-block:: cpp
+
+    #include <iostream>
+
+    #include <nghttp2/asio_http2_client.h>
+
+    using boost::asio::ip::tcp;
+
+    using namespace nghttp2::asio_http2;
+    using namespace nghttp2::asio_http2::client;
+
+    int main(int argc, char *argv[]) {
+      boost::system::error_code ec;
+      boost::asio::io_service io_service;
+
+      // connect to localhost:3000
+      session sess(io_service, "localhost", "3000");
+
+      sess.on_connect([&sess](tcp::resolver::iterator endpoint_it) {
+        boost::system::error_code ec;
+
+        auto req = sess.submit(ec, "GET", "http://localhost:3000/");
+
+        req->on_response([](const response &res) {
+          // print status code and response header fields.
+          std::cerr << "HTTP/2 " << res.status_code() << std::endl;
+          for (auto &kv : res.header()) {
+            std::cerr << kv.first << ": " << kv.second.value << "\n";
+          }
+          std::cerr << std::endl;
+
+          res.on_data([](const uint8_t *data, std::size_t len) {
+            std::cerr.write(reinterpret_cast<const char *>(data), len);
+            std::cerr << std::endl;
+          });
+        });
+
+        req->on_close([&sess](uint32_t error_code) {
+          // shutdown session after first request was done.
+          sess.shutdown();
+        });
+      });
+
+      sess.on_error([](const boost::system::error_code &ec) {
+        std::cerr << "error: " << ec.message() << std::endl;
+      });
+
+      io_service.run();
+    }
+
+For more details, see the documentation of libnghttp2_asio.
+
+Python bindings
+---------------
+
+The ``python`` directory contains nghttp2 Python bindings.  The
+bindings currently provide HPACK compressor and decompressor classes
+and an HTTP/2 server.
+
+The extension module is called ``nghttp2``.
+
+``make`` will build the bindings and target Python version is
+determined by the ``configure`` script.  If the detected Python version is not
+what you expect, specify a path to Python executable in a ``PYTHON``
+variable as an argument to configure script (e.g., ``./configure
+PYTHON=/usr/bin/python3.8``).
+
+The following example code illustrates basic usage of the HPACK compressor
+and decompressor in Python:
+
+.. code-block:: python
+
+    import binascii
+    import nghttp2
+
+    deflater = nghttp2.HDDeflater()
+    inflater = nghttp2.HDInflater()
+
+    data = deflater.deflate([(b'foo', b'bar'),
+                             (b'baz', b'buz')])
+    print(binascii.b2a_hex(data))
+
+    hdrs = inflater.inflate(data)
+    print(hdrs)
+
+The ``nghttp2.HTTP2Server`` class builds on top of the asyncio event
+loop.  On construction, *RequestHandlerClass* must be given, which
+must be a subclass of ``nghttp2.BaseRequestHandler`` class.
+
+The ``BaseRequestHandler`` class is used to handle the HTTP/2 stream.
+By default, it does nothing.  It must be subclassed to handle each
+event callback method.
+
+The first callback method invoked is ``on_headers()``.  It is called
+when HEADERS frame, which includes the request header fields, has arrived.
+
+If the request has a request body, ``on_data(data)`` is invoked for each
+chunk of received data.
+
+Once the entire request is received, ``on_request_done()`` is invoked.
+
+When the stream is closed, ``on_close(error_code)`` is called.
+
+The application can send a response using ``send_response()`` method.
+It can be used in ``on_headers()``, ``on_data()`` or
+``on_request_done()``.
+
+The application can push resources using the ``push()`` method.  It must be
+used before the ``send_response()`` call.
+
+The following instance variables are available:
+
+client_address
+    Contains a tuple of the form (host, port) referring to the
+    client's address.
+
+stream_id
+    Stream ID of this stream.
+
+scheme
+    Scheme of the request URI.  This is a value of :scheme header
+    field.
+
+method
+    Method of this stream.  This is a value of :method header field.
+
+host
+    This is a value of :authority or host header field.
+
+path
+    This is a value of :path header field.
+
+The following example illustrates the HTTP2Server and
+BaseRequestHandler usage:
+
+.. code-block:: python
+
+    #!/usr/bin/env python3
+
+    import io, ssl
+    import nghttp2
+
+    class Handler(nghttp2.BaseRequestHandler):
+
+        def on_headers(self):
+            self.push(path='/css/bootstrap.css',
+                      request_headers = [('content-length', '3')],
+                      status=200,
+                      body='foo')
+
+            self.push(path='/js/bootstrap.js',
+                      method='GET',
+                      request_headers = [('content-length', '10')],
+                      status=200,
+                      body='foobarbuzz')
+
+            self.send_response(status=200,
+                               headers = [('content-type', 'text/plain')],
+                               body=io.BytesIO(b'nghttp2-python FTW'))
+
+    ctx = ssl.SSLContext(ssl.PROTOCOL_SSLv23)
+    ctx.options = ssl.OP_ALL | ssl.OP_NO_SSLv2
+    ctx.load_cert_chain('server.crt', 'server.key')

-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.
