+
+Requirements
+
+- Windows
+- Python 2 or 3 with NumPy
+
+Installation
+
+Currently the wheel file has to be installed locally.
+
+If NumPy is not yet installed, install it using pip from the command line
+
+pip install numpy
+
+Then install pyCpufit from the local folder via:
+
+pip install --no-index --find-links=LocalPathToWheelFile pyCpufit
+
+Examples
+
+See project-root/examples/python folder. **Cpufit** examples begin with `cpufit_`.
