-## Description
+### Description
 
 This is a handy little tool for visualizing numeric series from the
 command-line, using 'sparklines'. Pass it a numeric series as arguments, and
 sparkl will display a sparkline graph, which you can use to very quickly get a
 sense of the shape of your data.

 * Crashes with 0 arguments. It'd be trivial to fix, but adds a few bytes to the
