+      This is a ported version of the <emphasis role="strong">Nix
+      Pills</emphasis>, a series of blog posts written by <emphasis
+      role="strong">Luca Bruno</emphasis> (aka Lethalman) and
+      orginally published in 2014 and 2015. It provides a tutorial

+      Since the Nix Pills are considered a classic introduction to
