 An efficient and light-weight ordered set of 32 bits integers.
 This is a Python wrapper for the C library `CRoaring <https://github.com/RoaringBitmap/CRoaring>`__.
 
-The wrapping used to be done with ``Ctypes``. We recently switched to
-``Cython`` for the following reasons:
+Example
+-------
 
--  Much better performances for short function calls (e.g.
-   addition/deletion of a single element).
--  Easier installation, no need to install manually the C library, it is
-   now distributed with PyRoaring.
--  Extensibility, it will be easier to write efficient codes with Cython
-   (e.g. some data structures based on roaring bitmaps).
+You can use a bitmap nearly as the classical Python set in your code:
 
-If for some reason you wish to keep using the old version, based on
-``Ctypes``, use `PyRoaring
-0.0.7 <https://github.com/Ezibenroc/PyRoaringBitMap/tree/0.0.7>`__.

--  Python 2.7, or Python 3.4 or better
--  A recent C compiler like GCC
--  The package manager ``pip``
--  The Python package ``hypothesis`` (optional, for testing)
--  The Python package ``Cython`` (optional, for compiling pyroaring from
-   the sources)
--  The Python package ``wheel`` (optional, to build a wheel for the library)

+Installation from Pypi
+----------------------

+Note: this installation method requires a recent C compiler like GCC.
+
+Supported systems:
+
+- Linux and MacOS: Python 2.7 or Python 3.4 or higher.
+- Windows: Python 3.4 or higher.
 
 To install pyroaring on your local account, use the following command:
 
 .. code:: bash
 
-    pip install pyroaring --user # installs PyRoaringBitMap

 If you want to use Python 3 and your system defaults on Python 2.7, you
 may need to adjust the above commands, e.g., replace ``pip`` by ``pip3``.
 
+Installation from the wheels
+----------------------------
+
+Several wheels are published on GitHub for each release:
+https://github.com/Ezibenroc/PyRoaringBitMap/releases
+
+Installing from a wheel should be the easiest as no C compiler is required. However, performance may be lower. Note that
+you have to chose the right wheel, depending on your system.
+
+For instance, to install ``pyroaring`` version ``0.2.1`` for Python ``3.6`` on Linux:
+
+.. code:: bash
+
+   pip install --user https://github.com/Ezibenroc/PyRoaringBitMap/releases/download/0.2.1/pyroaring-0.2.1-cp36-cp36m-linux_x86_64.whl
+
 Manual compilation / installation
 ---------------------------------
 
 If you want to compile (and install) pyroaring by yourself, for instance
 to modify the Cython sources or because you do not have ``pip``, follow
 these steps.
