-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();
-    }
-

-
-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')
-
-    # give None to ssl to make the server non-SSL/TLS
-    server = nghttp2.HTTP2Server(('127.0.0.1', 8443), Handler, ssl=ctx)
-    server.serve_forever()

+# Security Process
+
+If you find a vulnerability in our software, please report it via
+GitHub "Private vulnerability reporting" feature at
+https://github.com/nghttp2/nghttp2/security instead of submitting
+issues on github issue page.  It is a standard practice not to
+disclose vulnerability information publicly until a fixed version is
+released, or mitigation is worked out.
+
+If we identify that the reported issue is really a vulnerability, we
+open a new security advisory draft using [GitHub security
+feature](https://github.com/nghttp2/nghttp2/security) and discuss the
+mitigation and bug fixes there.  The fixes are committed to the
+private repository.
+
+We write the security advisory and get CVE number from GitHub
+privately.  We also discuss the disclosure date to the public.
+
+We make a new release with the fix at the same time when the
+vulnerability is disclosed to public.
+
+At least 7 days before the public disclosure date, we open a new issue
+on [nghttp2 issue tracker](https://github.com/nghttp2/nghttp2/issues)
+which notifies that the upcoming release will have a security fix.
+The `SECURITY` label is attached to this kind of issue.  The issue is
+not opened if a vulnerability is already disclosed, and it is publicly
+known that nghttp2 is affected by that.
+
+Before few hours of new release, we merge the fixes to the master
+branch (and/or a release branch if necessary) and make a new release.
+Security advisory is disclosed on GitHub.
