#### What is Integration ? Integration is considered to be any work that is "displayed" client side. There is a large grey area with what is considered integration, some people will consider building AppThemes as development. And this is not wrong, AppThemes can be very complex or very simple, but it's usually the integrator that changes CSS and design.
