## Introduction

The `meta-agl-demo` layer is the reference user interface layer for the DEMO
platform of Automotive Grade Linux (AGL).
The layer provides a reference platform and applications.
The BitBake target name for the DEMO platform is `agl-demo-platform`, which is
the full DEMO platform image.

## Layer Dependencies

This section describes dependencies for the `meta-agl-demo` layer.
Dependencies are grouped into base, hardware, and feature dependencies.
