-PyPICT
-======
-
-Python binding library for [Microsoft PICT](https://github.com/Microsoft/pict) (Pairwise Independent Combinatorial Tool).
-
-Installation
-------------
-
-```sh
-$ git clone https://github.com/kmaehashi/pypict.git
-$ cd pypict
-$ git submodule init
-$ git submodule update
-$ python setup.py build_pict
-$ pip install -U .

-APIs
-----
-
-There are four different APIs provided in this library.
-
-* Low-level API (``pypict.capi``) provides Python functions that map to each [PICT C API function](https://github.com/Microsoft/pict/blob/master/api/pictapi.h).
-* High-level API (``pypict.api``) wraps the low-level API to provide automatic memory management.
-* Tools API (``pypict.tools``) wraps the high-level API to provide convenient features.
-* Command API (``pypict.cmd``) is a thin wrapper for ``pict`` command.
-  Note that this API does not use features from PICT C API shared library.

+PyPICT
+======
+
+Python binding library for `Microsoft PICT <https://github.com/Microsoft/pict>`__ (Pairwise Independent Combinatorial Tool).
+
+Requirements
+------------
+
+* Microsoft PICT
+* Python 2.7, 3.4, 3.5 or 3.6
+
+Installation
+------------
+
+Wheels (binary distribution) are available for Linux.
+PICT shared library and command are included in wheels.
+
+::
+
+    $ pip install pypict
+
+On other platforms, you need to build from source.
+PICT source tree is registered as a submodule of this repository.
+``python setup.py build_pict`` will run ``make`` command to build PICT shared library inside the tree.
+You need to manually install the shared library and command, or set path of the tree to the appropriate environment variables (``PATH``, ``LD_LIBRARY_PATH``, etc.)
+
+::
+
+    $ git clone https://github.com/kmaehashi/pypict.git
+    $ cd pypict
+    $ git submodule init
+    $ git submodule update
+    $ python setup.py build_pict
+    $ pip install -U .
+    $ export PATH=${PWD}/pict:${PATH}
+    $ export LD_LIBRARY_PATH=${PWD}/pict:${LD_LIBRARY_PATH}
+
+APIs
+----
+
+There are four different APIs provided in this library.
+Generally, you only need to use Tools API (``pypict.tools``).
+
+* Low-level API (``pypict.capi``) provides Python functions that map to each `PICT C API function <https://github.com/Microsoft/pict/blob/master/api/pictapi.h>`__.
+* High-level API (``pypict.api``) wraps the low-level API to provide automatic memory management.
+* Tools API (``pypict.tools``) wraps the high-level API to provide convenient features.
+* Command API (``pypict.cmd``) is a thin wrapper for ``pict`` command.
+  This API uses PICT command directly instead of PICT shared library.
+
+Example
+-------
+
+Here is an example usage of Tools API to generate pair-wise patterns from parameter set.
+
+.. code-block:: python
+
+    import pypict.tools
+
+    params = {
+        "Type":          ["Single", "Span", "Stripe", "Mirror", "RAID-5"],
+        "Size":          ["10", "100", "500", "1000", "5000", "10000", "40000"],
+        "Format method": ["Quick", "Slow"],
+        "File system":   ["FAT", "FAT32", "NTFS"],
+        "Cluster size":  ["512", "1024", "2048", "4096", "8192", "16384", "32768", "65536"],
+        "Compression":   ["On", "Off"],
+    }
+
+    for case in pypict.tools.from_dict(params):
+        print(case)
