+
+`rundec-python` is a Python package providing a thin wrapper around `CRunDec`.
+
+## Installation
+
+```bash
+pip install rundec
+```
+
+## Usage
+
+The API is analogous to `CRunDec`, see [the documentation](https://arxiv.org/abs/1703.03751).
+
+```python
+import rundec
+
+crd = rundec.CRunDec
+
+# compute alpha_s at the b quark mass scale with 3-loop accuracy
+crd.AlphasExact(0.1185, 91.1876, 4.18, 5, 3)
+
+# compute the b quark pole mass using the 2-loop conversion from the MSbar mass
+crd.mMS2mOS(4.18, None,  0.26, 4.18, 5, 2)
+```
+
+## Technical details
+
+The wrapper was generated with [SWIG](http://www.swig.org/).
+
+Binary wheels are provided via [PyPI](https://pypi.python.org/pypi/rundec) for Linux and Mac OS (built on [Travis CI](https://travis-ci.org/)) and for Windows (built on [AppVeyor](https://www.appveyor.com/)).
+
+The Windows wheels require Python 3.5+, on Linux and Mac OS Python 2.7+ is sufficient.
