# Introduction

DMG Canvas builds disk images from template documents that you create. Each template defines the properties of the Finder window for the disk image (including the size and background color or image), the files in the disk image (including their icon size and positions in the window), and the name, icon, format, and encryption settings of the disk image volume. DMG Canvas also allows you to specify the license agreements displayed when the disk image is mounted.

Each time you build the disk image, the latest versions of the files you added are copied into the disk image. The disk image can then be code signed and notarized, ready for deployment for all versions of macOS.
