Configuring an IntelliJ Beta-testing Environment From Scratch

WIP - Proper formatting, better explanations, and images to be added later (but this should do for now) 
 Preparation: 
 Download and install IntelliJ (Community Edition). Download and install Java 8. 
 Setting up IntelliJ: 
 
 Clone the Zora no Densha repository into an empty folder. 
 Using either the command line or a Git management tool (such as GitKraken), switch the branch of the downloaded repository to  mc-1.7.10 . 
 Start IntelliJ and open the downloaded repository's folder as the current project. Allow IntelliJ to 'trust' the folder/project if such a warning appears. 
 Allow the project to automatically configure itself. There should be a progress bar or status message within IntelliJ advising that the project is currently importing. 
 Once the project is fully imported and no other tasks are running in the background, add a Run Configuration to IntelliJ to be able to start the game. A Gradle run configuration should be added with the task  runClient . 
 Change Gradle Java version to 1.8 (elephant on the right, then the small cogwheel) 
 Start the game using the  Debug function in IntelliJ.
