 ## dicepwgen - A diceware password generator
 
-This is the README file for the password generator dicepwgen.
+`dicepwgen` generates a [diceware password](https://de.wikipedia.org/wiki/Diceware)
+using a dictionary file. By default it uses pseudo random dice tosses,
+but it is also possible to use real dices and enter the numbers by using
+the option `-t`, which is the most secure way to generate diceware passwords.
