+## Table of Contents

+- [`vcpkg-eg-mac` VMs](#vcpkg-eg-mac-vms)
+  - [Table of Contents](#table-of-contents)
+  - [Basic Usage](#basic-usage)
+  - [Setting up a new macOS machine](#setting-up-a-new-macos-machine)
+
+## Basic Usage
+
+The simplest usage, and one which should be used for when spinning up
+new VMs, and when restarting old ones, is a simple:
+
+```
+$ cd ~/vagrant/vcpkg-eg-mac
+$ vagrant up
+```
+
+Any modifications to the machines should be made in `configuration/VagrantFile`
+and `Setup-VagrantMachines.ps1`, and make sure to push any changes!
+
+## Setting up a new macOS machine
+
+Before anything else, one must download `brew` and `powershell`.
+
+```sh
+$ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
+$ brew cask install powershell
+```
+
+Then, we need to download the `vcpkg` repository:
+
+```sh
+$ git clone https://github.com/microsoft/vcpkg
+```
+
+And now all we need to do is set it up! Replace `XX` with the number of
+the virtual machine. Generally, that should be the same as the number
+for the physical machine; i.e., vcpkgmm-04 will have vcpkg-eg-mac-04.
+
+```sh
+$ cd vcpkg/scripts/azure-pipelines/osx
+$ ./Install-Prerequisites.ps1 -Force
+  # NOTE: you may get an error about CoreCLR; see the following paragraph if you do
+$ ./Setup-VagrantMachines.ps1 XX \
+  -Pat '<get this from azure>' \
+  -ArchivesUsername '<get this from the archives share>' \
+  -ArchivesAccessKey '<get this from the archives share>' \
+  -ArchivesUri '<something>.file.core.windows.net' \
+  -ArchivesShare 'archives'
+$ cd ~/vagrant/vcpkg-eg-mac
+$ vagrant up
+```
+
+If you see the following error:
+
+```
+Failed to initialize CoreCLR, HRESULT: 0x8007001F
+```
+
+You have to reboot the machine; run
+
+```sh
+$ sudo shutdown -r now
+```
+
+and wait for the machine to start back up. Then, start again from
+`Install-Prerequisites.ps1`.
