+		Black is the uncompromising Python code formatter. By using it, you agree
+		to cede control over minutiae of hand-formatting. In return, Black gives
+		you speed, determinism, and freedom from pycodestyle nagging about formatting.
+		You will save time and mental energy for more important matters.
