+      CSSLint is a tool to help point out problems with your CSS
+      code. It does basic syntax checking as well as applying a set of
+      rules to the code that look for problematic patterns or signs of
+      inefficiency. The rules are all pluggable, so you can easily
+      write your own or omit ones you don't want. '';
