+
+Psycopg is the most popular PostgreSQL database adapter for the Python
+programming language.  Its main features are the complete implementation of
+the Python DB API 2.0 specification and the thread safety (several threads can
+share the same connection).  It was designed for heavily multi-threaded
+applications that create and destroy lots of cursors and make a large number
+of concurrent "INSERT"s or "UPDATE"s.
+
+Psycopg 2 is mostly implemented in C as a libpq wrapper, resulting in being
+both efficient and secure.  It features client-side and server-side cursors,
+asynchronous communication and notifications, "COPY TO/COPY FROM" support.
+Many Python types are supported out-of-the-box and adapted to matching
+PostgreSQL data types; adaptation can be extended and customized thanks to a
+flexible objects adaptation system.
+
+Psycopg 2 is both Unicode and Python 3 friendly.

+Documentation
+-------------
+
+Documentation is included in the ``doc`` directory and is `available online`__.
+
+.. __: https://www.psycopg.org/docs/
+
+For any other resource (source code repository, bug tracker, mailing list)
+please check the `project homepage`__.
+
+.. __: https://psycopg.org/
+
+
+Installation
+------------
+
+Building Psycopg requires a few prerequisites (a C compiler, some development
+packages): please check the install_ and the faq_ documents in the ``doc`` dir
+or online for the details.
+
+If prerequisites are met, you can install psycopg like any other Python
+package, using ``pip`` to download it from PyPI_::
+
+    $ pip install psycopg2
+
+or using ``setup.py`` if you have downloaded the source package locally::
+
+    $ python setup.py build
+    $ sudo python setup.py install
+
+You can also obtain a stand-alone package, not requiring a compiler or
+external libraries, by installing the `psycopg2-binary`_ package from PyPI::
+
+    $ pip install psycopg2-binary
+
+The binary package is a practical choice for development and testing but in
+production it is advised to use the package built from sources.

+"""A Python driver for PostgreSQL
+
+psycopg is a PostgreSQL_ database adapter for the Python_ programming
+language. This is version 2, a complete rewrite of the original code to
+provide new-style classes for connection and cursor objects and other sweet
+candies. Like the original, psycopg 2 was written with the aim of being very
+small and fast, and stable as a rock.
