+
+Multidict is dict-like collection of *key-value pairs* where key
+might be occurred more than once in the container.
+
+Introduction
+------------
+
+*HTTP Headers* and *URL query string* require specific data structure:
+*multidict*. It behaves mostly like a regular ``dict`` but it may have
+several *values* for the same *key* and *preserves insertion ordering*.
+
+The *key* is ``str`` (or ``istr`` for case-insensitive dictionaries).
+
+``multidict`` has four multidict classes:
+``MultiDict``, ``MultiDictProxy``, ``CIMultiDict``
+and ``CIMultiDictProxy``.
+
+Immutable proxies (``MultiDictProxy`` and
+``CIMultiDictProxy``) provide a dynamic view for the
+proxied multidict, the view reflects underlying collection changes. They
+implement the ``collections.abc.Mapping`` interface.
+
+Regular mutable (``MultiDict`` and ``CIMultiDict``) classes
+implement ``collections.abc.MutableMapping`` and allows to change
+their own content.
+
+
+*Case insensitive* (``CIMultiDict`` and
+``CIMultiDictProxy``) ones assume the *keys* are case
+insensitive, e.g.::
+
+   >>> dct = CIMultiDict(key='val')
+   >>> 'Key' in dct
+   True
+   >>> dct['Key']
+   'val'
+
+*Keys* should be ``str`` or ``istr`` instances.
+
+The library has optional C Extensions for sake of speed.

+License

+
+Apache 2
+
+Library Installation
+--------------------
+
+.. code-block:: bash
+
+   $ pip install multidict
+
+The library is Python 3 only!
+
+PyPI contains binary wheels for Linux, Windows and MacOS.  If you want to install
+``multidict`` on another operation system (or *Alpine Linux* inside a Docker) the
+Tarball will be used to compile the library from sources.  It requires C compiler and
+Python headers installed.
+
+To skip the compilation please use `MULTIDICT_NO_EXTENSIONS` environment variable,
+e.g.:
+
+.. code-block:: bash
+
+   $ MULTIDICT_NO_EXTENSIONS=1 pip install multidict
+
+Please note, Pure Python (uncompiled) version is about 20-50 times slower depending on
+the usage scenario!!!
