 ### Introduction
 
 Welcome to the first exercise on the Java track!
 
-This document is a step-by-step guide to solving this exercise. The instructions should work equally well on Windows, macOS and Linux.

 Even if you are already familiar with Java basics, stepping through this guide may be helpful as it will help you understand the output from the tool, Gradle, that we use to compile and test our code, as well as introduce some of the patterns common to all exercises in this track.
 
 ### Exercise Structure
 
 When you fetch a new Java exercise, you will receive:
 
-- __one or more test files__ (always). These live in the `src/test/java` directory and define a set of tests that our solution must satisfy before we can safely declare that it is working.
-- __one or more starter files__ (initially). If provided, these live in the `src/main/java` directory and define shells of the classes you will need in order to solve the current problem.

 ### Become a mentor
 
-The heart of Exercism are the conversations about coding practices. It's definitely fun to practice, but engaging with others both in their attempts and your own is how you get feedback. That feedback can help point out what you're doing well and where you might need to improve.
