Add the plugin to a new project
To launch Unreal Engine, open the Epic Games launcher and click on Unreal Engine > Launch. When you launch Unreal Engine (UE4), the Unreal Project Browser automatically opens.
Under New Project Categories, select the development category that best matches your industry.
Select a template for your project, then click Next. The Project Settings page displays. We recommend using a blank template to initialize the plugin.
On the Project Settings page, you can select the quality/performance level, target platform, whether to include Starter Content, and more.
Set the project to a C++ project. This will create a visual studio project to develop code in and fulfills the requirement to have at least one empty C++ class in the source code folder. View the Deployment page for more information.
At the bottom of the Project Settings page, select where you want to store your project, and give your project a name. Click Create Project to finish.
For more information on project settings see Create a New Project from Unreal Engine 4 Documentation.
