+    """Scikit-Optimize, or skopt, is a simple and efficient library to
+       minimize (very) expensive and noisy black-box functions. It implements
+       several methods for sequential model-based optimization. skopt aims to
+       be accessible and easy to use in many contexts.
+
+       The library is built on top of NumPy, SciPy and Scikit-Learn."""
