+    """Polypolish is a tool for polishing genome assemblies with short reads.
+    Unlike other tools in this category, Polypolish uses SAM files where each
+    read has been aligned to all possible locations (not just a single best
+    location). This allows it to repair errors in repeat regions that other
+    alignment-based polishers cannot fix."""
