+To add Apps you will need to build a custom container with the App(s) installed.  There are multiple ways to add an App to your environment but this document will describe two options, the first is the [standard method pulling from PyPI](#adding-apps-using-pypi) and the second will be to [using the `plugins` folder](#adding-apps-using-plugins-folder).
 
 ## Getting Started Using Apps
