+    """HDBSCAN - Hierarchical Density-Based Spatial Clustering of
+    Applications with Noise. Performs DBSCAN over varying epsilon
+    values and integrates the result to find a clustering that gives
+    the best stability over epsilon. This allows HDBSCAN to find
+    clusters of varying densities (unlike DBSCAN), and be more robust
+    to parameter selection. In practice this means that HDBSCAN
+    returns a good clustering straight away with little or no
+    parameter tuning -- and the primary parameter, minimum cluster
+    size, is intuitive and easy to select.  HDBSCAN is ideal for
+    exploratory data analysis; it's a fast and robust algorithm that
+    you can trust to return meaningful clusters (if there are any)."""
