-You̇r screen is quiṭe dirty, please cleȧn it.
+Thoughts o̒f dirt sp̒ill over to̒ your unicode enabled ̇tex̒t.̣
+
+Usage:
+
+ --feinstaub
+ 	spray dust on your text
+
+ --grobe-mettwurst
+ 	a cookie got mangled in your typewriter
+
+ --nein-nein-nein
+ 	this is unacceptable
+
+ -p 0.1
+	probability between 0.0 and 1.0
+
+Everything is optional, all options can be combined. If nothing
+is defined, the program defaults to the runes for --feinstaub.
+
+The random number generator is not seeded.
