+# Hello World
+
+The classical introductory exercise. Just say "Hello, World!".
+
+["Hello, World!"](http://en.wikipedia.org/wiki/%22Hello,_world!%22_program) is
+the traditional first program for beginning programming in a new language
+or environment.
+
+The objectives are simple:
+
+- Write a function that returns the string "Hello, World!".
+- Run the test suite and make sure that it succeeds.
+- Submit your solution and check it at the website.
+
+If everything goes well, you will be ready to fetch your first real exercise.
+
+# Tips
+
+Since this is your first Java exercise, we've included a detailed TUTORIAL.md
+file that guides you through your solution. Check it out for tips and
+assistance!
+
+
+
+## Setup
+
+Go through the setup instructions for Java to install the necessary
+dependencies:

+
+# Running the tests
+
+You can run all the tests for an exercise by entering the following in your
+terminal:
+
+```sh
+$ gradle test
+```
+
+> Use `gradlew.bat` if you're on Windows
+
+In the test suites all tests but the first have been skipped.
+
+Once you get a test passing, you can enable the next one by removing the
+`@Ignore("Remove to run test")` annotation.
