+Overview
+========
+
+Introduction
+------------
+
+**Py-Enigma** is a Python 3 library for simulating the `Enigma machines`_ used
+by the German armed forces (*Wehrmacht*) during World War II. Py-Enigma is
+historically accurate, meaning it can interoperate with actual Wehrmacht Enigma
+machines. In other words, Py-Enigma can decrypt coded messages created with an
+actual Enigma, and it can encrypt messages that an actual Enigma can decode.
+
+It is hoped that this library will be useful to Enigma enthusiasts, historians,
+and students interested in cryptography.
+
+Py-Enigma strives to be Pythonic, easy to use, and comes with both unit tests
+and documentation. Py-Enigma is a library for building applications for
+encrypting and decrypting Enigma messages. However, it also ships with a simple
+command-line application that can encrypt & decrypt messages for scripting and
+experimentation.
+
+Scope
+-----
+
+Currently, Py-Enigma simulates the Wehrmacht Enigma machines. This includes the
+3 and 4 rotor machines used by the German Army (*Heer*), Air Force
+(*Luftwaffe*), and Navy (*Kriegsmarine*). Simulation of other Enigma models,
+including the various commercial, railroad, foreign market, and Abhwer (Military
+Intelligence) models may come later if there is enough interest and data
+available.
+
+Quick Example
+-------------
+
+This example shows how the library can be used to decode a message using the
+procedure employed by the German army
+
+.. literalinclude:: ../../examples/example1.py
+   
+This program prints::
+
+   THEXRUSSIANSXAREXCOMINGX
+
+Py-Enigma also includes a command-line application for processing messages.
+Assuming you have a proper key file that contains the same initial settings as
+the code above, the above example can be performed on the command-line::
+
+   $ pyenigma.py --key-file=keys.txt --start=WXC --text='KCH'
+   BLA
+   $ pyenigma.py --key-file=keys.txt --start=BLA --text='NIBLFMYMLLUFWCASCSSNVHAZ'
+   THEXRUSSIANSXAREXCOMINGX
+
+The format of the key file can be found in the documentation for pyenigma.py.
+
+Requirements
+------------
+
+Py-Enigma is written in Python_, specifically Python 3.2. It has no other
+requirements or dependencies.
+
+Installation
+------------
+
+To install or upgrade via PyPI_ use pip_::
+
+   pip install pyenigma             # install
+   pip install --upgrade pyenigma   # upgrade
+
+Alternatively you can download a source .zip or tarball at the `Py-Enigma
+Bitbucket page`_. Once unpacked, you can install with::
+
+   python setup.py install
+
+
+Support & Source
+----------------
+
+All support takes place at the `Py-Enigma Bitbucket page`_. Please enter any
+feature requests or bugs into the `issue tracker`_.
+
+You may also clone the Mercurial_ source code repository::
+
+   $ hg clone https://bitbucket.org/bgneal/enigma
+
+
+Acknowledgements & References
+-----------------------------
+
+This software would not have been possible without the thorough and detailed
+descriptions of the Enigma machine on Dirk Rijmenants' incredible `Cipher
+Machines and Cryptology website`_. In particular, his `Technical Details of the
+Enigma Machine`_ page was a gold mine of information.
+
+Dirk has also written an `Enigma simulator`_ in Visual Basic. Although I did not
+look at his source code, I did use his simulator to check the operation of
+Py-Enigma.
+
+I would also like to recommend the photos and video at Dr. Thomas B. Perera's
+`Enigma Museum`_.
+
+Another good website is `The Enigma and the Bombe`_ by Graham Ellsbury.
+
+A nice video which shows the basic components and operation of the Enigma
+Machine is on YouTube: `Nadia Baker & Enigma demo`_.
