-[Hangman](https://en.wikipedia.org/wiki/Hangman_%28game%29) is a words
-guessing game for one player. The computer guesses a word and the user
-has to suggest letters one by one. Every time the word contains a letter,
-the computer opens it (all of them, if there are a few). Every time the
-word doesn't contain a letter, the computer gives a penalty point for
-the user. If there are five penalty points, the user looses. If there
-are no hidden letters anymore, the computer looses.
-
-First, build it:
-
-```
-$ mvn clean package
-```
-
-Then, run:
-
-```
-$ java -classpath target/classes hangman.Main
-```
-
-This Java code is very procedural, imperative and not elegant at all.
-
-Please, try to refactor it and improve. You're welcome to create new classes,
-new methods, anything. Just make sure it still builds.
-
-When ready, please submit a pull request.
