Before we begin you must have:

• A Legally bought copy of Pistol Whip bought through the Oculus Store.
• A 64-Bit Windows Computer. To Check, enter the Control Panel → System and Security → System. Under 'System type:' If both your Operating System and Processor are 64bit / x64, you should be fine. If not then you, unfortunately, are unable to continue this guide at this moment in time. (Unless you have knowledge on how to extract & compile 64-bit Applications within your operating system)
• The 64-Bit Version of Java. If needed, installation will be explained later in the guide.
• A USB-A to USB-C Cable to connect your Quest to your Computer.

1. Enable Developer mode & Download SideQuest.

If you've already enabled developer mode / have already modded games such as Beat Saber or Synth Riders, you can skip this step.

Firstly, Enable developer mode within your headset. There are already plenty of guides on how to do this:
