+--------------------------------
+ MacOS CI Virtual Image Builder
+--------------------------------
+
+This package contains a script that can build provisioned virtual box images
+that contain a minimal installation of macOS for CI purposes. To build such
+images you'll need:
+
+* A computer running macOS (you can only virtualize macOS on another computer
+  running macOS)
+* A recent version of Packer_
+* The app for the OS you'll want to install. You can obtain installers for most
+  macOS versions through the AppStore. Just install the app through the
+  AppStore on the computer running this script.
+* The `Xcode SDK`_ you'll need installed on the image, downloaded to the
+  ``xcode`` subdirectory of this package. For example, to download the latest
+  release of macOS 10.9 (Mavericks) SDK, do this::
+
+  $ mkdir xcode && cd xcode
+  $ wget https://github.com/phracker/MacOSX-SDKs/releases/download/10.13/MacOSX10.9.sdk.tar.xz
+
+Once all is in place, run the ``build.sh`` command, passing the version of
+macOS you wish to build an image for::
+
+  $ ./build.sh 10.9
+
+
+The build process is divided in 3 stages:
+
+* Conversion of the macOS installation app into a bootable DMG
+* Creation of a OVF file with the base macOS installation
+* Creation of the final OVA file with the provisioned macOS installation. The
+  provisioning consists of the execution, in sequence, of all scripts in the
+  ``scripts`` directory.
+
+The virtual image, when ready, will be available at the ``ova`` directory.
+
+
+Deployment
+==========
+
+To deploy the newly created virtual image, follow the procedure on configuring
+a `VirtualBox Executor`_ for gitlab CI.
