+### Python module
+JSBSim provides binary packages (a.k.a. known as [wheel packages](https://www.python.org/dev/peps/pep-0427)) for its Python module on Windows and Linux platforms for several Python versions (3.5, 3.6, 3.7 and 3.8).
+
+The module is installed with the `pip` command line (check the [pip documentation](https://packaging.python.org/tutorials/installing-packages) for more details):
+```bash
+> pip install jsbsim --no-index -f https://github.com/JSBSim-Team/jsbsim/releases/download/Rolling-release-v2019/JSBSim-1.1.0.dev1-cp37-cp37m-manylinux1_x86_64.whl
+```
+The example above downloads and installs JSBSim for Python 3.7 on a Linux platform directly from the JSBSim GitHub project page. The package corresponding to your platform and Python version must be picked among all the available JSBSim wheel packages that are listed in the [Releases page](https://github.com/JSBSim-Team/jsbsim/releases/tag/Rolling-release-v2019).
+
+Note that wheel packages for Linux meet the [ManyLinux packages requirements](https://www.python.org/dev/peps/pep-0513) and as such are compatible with all the major Linux distributions.
 ### Other platforms
 At the moment, JSBSim do not provide binaries for platforms other than Windows 64 bits and Ubuntu 16.04 64 bits. If you fall in this category you should follow the instructions in the [developer docs](doc/DevelopersDocs.md) to build JSBSim on your platform.
