Developing the remote-controlled ship

Let's start by importing the existing Git repository.

Project setup

Let's start setting up the project:

  1. Open IntelliJ IDEA. If an existing project is already opened, select File | Close Project.

    You will be presented with a screen similar to the following:

  2. To import the project from the Git repository, click on Check out from Version Control and select Git. Type https://bitbucket.org/vfarcic/tdd-java-ch04-ship.git in to the Git Repository URL field and click on Clone:
