This directory contains the configuration files for all predefined packages and instructions on building them.
To learn how to build the predefined provisioning packages, see Building Provisioning Packages. You can see more details on each package by navigating to its directory and reading its readme.
Each provisioning package is defined by a customizations.xml file.
ICD uses this file as a blueprint for building the resulting package.
The resulting package is outputted as a .ppkg file, along with a .cat file.
The .cat file contains basic information about the package, but is generally useless unless you are password protecting or signing your package with a certificate.
The .ppkg file contains all scripts, assets, and binaries and is used to provision a device during or after Windows OOBE.
For more information, see Provisioning packages for Windows.
