# Launcher Interface

Launcher Module consists of the following sections: 

**Launch Configurations**: The section where you can Add and Delete a launch configuration. Changing the Configuration Mode, launching, stopping, and re-timing an engine also occurs inside the Launch Configuration section.

**Renderers**: It is the section where you can specify the details of your project to be rendered.
