+Package sprig provides template functions for Go.
+
+This package contains a number of utility functions for working with data
+inside of Go `html/template` and `text/template` files.
+
+To add these functions, use the `template.Funcs()` method:
+
+	t := templates.New("foo").Funcs(sprig.FuncMap())
+
+Note that you should add the function map before you parse any template files.
+
+	In several cases, Sprig reverses the order of arguments from the way they
+	appear in the standard library. This is to make it easier to pipe
+	arguments into functions.
+
+See http://masterminds.github.io/sprig/ for more detailed documentation on each of the available functions.
