+### Practice Project
+
+For the final part of your Java training, you will build a program that reads user input from the console and  
+does something cool. This is a vague goal, so it's up to you to figure out what you want to make. It can be  
+relatively small and simple but try to actually use everything you learned.
+
+Example Ideas:
+
+* Currency Converter (user gives amount and currency input, converter gives output in given currency)
+* Number Guessing Game (program picks random number, user tries to guess it while program gives hints)
