Added version release notes

Necessary due to it looking like
[SPDX](https://github.com/spdx/license-list-XML/issues/1393) might not
approve the 3.0.0 version. The 2.1.0 version will have to suffice as a
safe fallback which won't cause conflicts with downstream tooling.

+= Hippocratic License
+
+Version: 2.1.0.
+
+Purpose. The purpose of this License is for the Licensor named above to
+permit the Licensee (as defined below) broad permission, if consistent
+with Human Rights Laws and Human Rights Principles (as each is defined
+below), to use and work with the Software (as defined below) within the
+full scope of Licensor’s copyright and patent rights, if any, in the
+Software, while ensuring attribution and protecting the Licensor from
+liability.
+
+Permission and Conditions. The Licensor grants permission by this
+license ("License"), free of charge, to the extent of Licensor’s
+rights under applicable copyright and patent law, to any person or
+entity (the "Licensee") obtaining a copy of this software and
+associated documentation files (the "Software"), to do everything with
+the Software that would otherwise infringe (i) the Licensor’s copyright
+in the Software or (ii) any patent claims to the Software that the
+Licensor can license or becomes able to license, subject to all of the
+following terms and conditions:
+
+* Acceptance. This License is automatically offered to every person and
+entity subject to its terms and conditions. Licensee accepts this
+License and agrees to its terms and conditions by taking any action with
+the Software that, absent this License, would infringe any intellectual
+property right held by Licensor.
+* Notice. Licensee must ensure that everyone who gets a copy of any part
+of this Software from Licensee, with or without changes, also receives
+the License and the above copyright notice (and if included by the
+Licensor, patent, trademark and attribution notice). Licensee must cause
+any modified versions of the Software to carry prominent notices stating
+that Licensee changed the Software. For clarity, although Licensee is
+free to create modifications of the Software and distribute only the
+modified portion created by Licensee with additional or different terms,
+the portion of the Software not modified must be distributed pursuant to
+this License. If anyone notifies Licensee in writing that Licensee has
+not complied with this Notice section, Licensee can keep this License by
+taking all practical steps to comply within 30 days after the notice. If
+Licensee does not do so, Licensee’s License (and all rights licensed
+hereunder) shall end immediately.
+* Compliance with Human Rights Principles and Human Rights Laws.
+[arabic]
+. Human Rights Principles.
+[loweralpha]
+.. Licensee is advised to consult the articles of the United Nations
+Universal Declaration of Human Rights and the United Nations Global
+Compact that define recognized principles of international human rights
+(the "Human Rights Principles"). Licensee shall use the Software in a
+manner consistent with Human Rights Principles.
+.. Unless the Licensor and Licensee agree otherwise, any dispute,
+controversy, or claim arising out of or relating to (i) Section 1(a)
+regarding Human Rights Principles, including the breach of Section 1(a),
+termination of this License for breach of the Human Rights Principles,
+or invalidity of Section 1(a) or (ii) a determination of whether any Law
+is consistent or in conflict with Human Rights Principles pursuant to
+Section 2, below, shall be settled by arbitration in accordance with the
+Hague Rules on Business and Human Rights Arbitration (the "Rules");
+provided, however, that Licensee may elect not to participate in such
+arbitration, in which event this License (and all rights licensed
+hereunder) shall end immediately. The number of arbitrators shall be one
+unless the Rules require otherwise.
++
+Unless both the Licensor and Licensee agree to the contrary: (1) All
+documents and information concerning the arbitration shall be public and
+may be disclosed by any party; (2) The repository referred to under
+Article 43 of the Rules shall make available to the public in a timely
+manner all documents concerning the arbitration which are communicated
+to it, including all submissions of the parties, all evidence admitted
+into the record of the proceedings, all transcripts or other recordings
+of hearings and all orders, decisions and awards of the arbitral
+tribunal, subject only to the arbitral tribunal’s powers to take such
+measures as may be necessary to safeguard the integrity of the arbitral
+process pursuant to Articles 18, 33, 41 and 42 of the Rules; and (3)
+Article 26(6) of the Rules shall not apply.
+. Human Rights Laws. The Software shall not be used by any person or
+entity for any systems, activities, or other uses that violate any Human
+Rights Laws. "Human Rights Laws" means any applicable laws,
+regulations, or rules (collectively, "Laws") that protect human,
+civil, labor, privacy, political, environmental, security, economic, due
+process, or similar rights; provided, however, that such Laws are
+consistent and not in conflict with Human Rights Principles (a dispute
+over the consistency or a conflict between Laws and Human Rights
+Principles shall be determined by arbitration as stated above). Where
+the Human Rights Laws of more than one jurisdiction are applicable or in
+conflict with respect to the use of the Software, the Human Rights Laws
+that are most protective of the individuals or groups harmed shall
+apply.
+. Indemnity. Licensee shall hold harmless and indemnify Licensor (and
+any other contributor) against all losses, damages, liabilities,
+deficiencies, claims, actions, judgments, settlements, interest, awards,
+penalties, fines, costs, or expenses of whatever kind, including
+Licensor’s reasonable attorneys’ fees, arising out of or relating to
+Licensee’s use of the Software in violation of Human Rights Laws or
+Human Rights Principles.
+* Failure to Comply. Any failure of Licensee to act according to the
+terms and conditions of this License is both a breach of the License and
+an infringement of the intellectual property rights of the Licensor
+(subject to exceptions under Laws, e.g., fair use). In the event of a
+breach or infringement, the terms and conditions of this License may be
+enforced by Licensor under the Laws of any jurisdiction to which
+Licensee is subject. Licensee also agrees that the Licensor may enforce
+the terms and conditions of this License against Licensee through
+specific performance (or similar remedy under Laws) to the extent
+permitted by Laws. For clarity, except in the event of a breach of this
+License, infringement, or as otherwise stated in this License, Licensor
+may not terminate this License with Licensee.
+* Enforceability and Interpretation. If any term or provision of this
+License is determined to be invalid, illegal, or unenforceable by a
+court of competent jurisdiction, then such invalidity, illegality, or
+unenforceability shall not affect any other term or provision of this
+License or invalidate or render unenforceable such term or provision in
+any other jurisdiction; provided, however, subject to a court
+modification pursuant to the immediately following sentence, if any term
+or provision of this License pertaining to Human Rights Laws or Human
+Rights Principles is deemed invalid, illegal, or unenforceable against
+Licensee by a court of competent jurisdiction, all rights in the
+Software granted to Licensee shall be deemed null and void as between
+Licensor and Licensee. Upon a determination that any term or provision
+is invalid, illegal, or unenforceable, to the extent permitted by Laws,
+the court may modify this License to affect the original purpose that
+the Software be used in compliance with Human Rights Principles and
+Human Rights Laws as closely as possible. The language in this License
+shall be interpreted as to its fair meaning and not strictly for or
+against any party.
+* Disclaimer. TO THE FULL EXTENT ALLOWED BY LAW, THIS SOFTWARE COMES

+= macOS
+
+Shell scripts for automated macOS machine setup.
+
+This project is a framework for automating the setup of a macOS machine. In order to illustrate the
+potential of what this project can do, please see the companion
+link:https://www.alchemists.io/projects/mac_os-config[macOS Config] project for details. The _macOS
+Config_ project is an opinionated configuration which meets the needs of my development environment
+but is also meant to serve as an example and guide for building your own personalized setup. Here is
+how the two projects are meant to be used:
+
+* *macOS* (this project) - The foundational framework for building custom macOS machine setups.
+* *link:https://www.alchemists.io/projects/mac_os-config[macOS Configuration]* - The layer on top of
+  this _macOS_ project which defines a custom machine implementation. The project is meant to be
+  forked for as many custom machine setups as needed.
+
+toc::[]
+

+
+== Requirements
+
+. link:https://www.apple.com/macos/monterey[macOS Monterey]
+. link:https://developer.apple.com/xcode[Xcode]
+
+== Setup
+
+To install, run:
+
+[source,bash]
+----
+git clone https://github.com/bkuhlmann/mac_os.git
+cd mac_os
+git checkout 15.0.2
+----
+
+== Usage
+
+Run the following:
+
+[source,bash]
+----
+bin/run
+----
+
+You will be presented with the following options (listed in order of
+use):
+
+....
+Boot:
+   B:  Create boot disk.
+Install:
+   b:  Apply basic settings.
+   t:  Install development tools.
+  hf:  Install Homebrew Formulas.
+  hc:  Install Homebrew Casks.
+   m:  Install Mac App Store software.
+   a:  Install application software.
+   x:  Install application software extensions.
+  df:  Install dotfiles.
+  np:  Install Node packages.
+  rg:  Install Ruby gems.
+  rc:  Install Rust crates.
+   d:  Apply default settings.
+  cs:  Configure installed software.
+   i:  Install everything (i.e. executes all install options in order listed).
+Restore:
+   R:  Restore settings from backup.
+Manage:
+   c:  Check status of managed software.
+   C:  Caffeinate machine.
+  ua:  Uninstall application software.
+  ux:  Uninstall application software extension.
+  ra:  Reinstall application software.
+  rx:  Reinstall application software extension.
+   w:  Clean work (temp) directory.
+   q:  Quit/Exit.
+....
+
+Choose option `i` to run a full install or select a specific option to run a single action. Each
+option is designed to be re-run if necessary. This can also be handy for performing upgrades,
+re-running a missing/failed install, etc.
+
+The option prompt can be skipped by passing the desired option directly to the `bin/run` script. For
+example, executing `bin/run i` will execute the full install process.
+
+The machine should be rebooted after all install tasks have completed to ensure all settings have
+been loaded.
+
+It is recommended that the `mac_os` project directory not be deleted and kept on the local machine
+in order to manage installed software and benefit from future upgrades.
+
+=== Boot Disk
+
+When attempting to create a boot disk via `bin/run B`, you’ll be presented with the following
+documentation (provided here for reference):
+
+....
+macOS Boot Disk Tips
+  - Use a USB drive (8GB or higher).
+  - Use Disk Utility to format the USB drive as "Mac OS Extended (Journaled)".
+  - Use Disk Utility to label the USB drive as "Untitled".
+
+macOS Boot Disk Usage:
+  1. Insert the USB boot disk into the machine to be upgraded.
+  2. Reboot the machine.
+  3. Hold the POWER (Silicon) or OPTION (Intel) key before the Apple logo appears.
+  4. Select the USB boot disk from the menu.
+  5. Use Disk Utility to delete and/or erase the hard drive including associated partitions.
+  6. Use Disk Utility to create a single "APFS" drive as a "GUID Partition Table".
+  7. Install the new operating system.
+
+macOS Boot Disk Recovery:
+  1. Start/restart the machine.
+  2. Hold the POWER (Silicon) or COMMAND+R (Intel) keys before the Apple logo appears.
+  3. Wait for the macOS installer to load from the recovery partition.
+  4. Use the dialog options to launch Disk Utility, reinstall the system, etc.
+....
+
+=== Customization
+
+All executable scripts can be found in the `bin` folder:
+
+* `bin/apply_basic_settings` (optional, customizable): Applies basic and initial settings for
+  setting up a machine.
+* `bin/apply_default_settings` (optional, customizable): Applies bare minimum system and application
+  defaults.
+* `bin/configure_software` (optional, customizable): Configures installed software as part of the
+  post install process.
+* `bin/create_boot_disk` (optional): Creates a macOS boot disk.
+* `bin/install_app_store` (optional, customizable): Installs macOS, GUI-based, App Store
+  applications.
+* `bin/install_applications` (optional, customizable): Installs macOS, GUI-based, non-App Store
+  applications.
+* `bin/install_dev_tools` (required): Installs macOS development tools required by Homebrew.
+* `bin/install_dotfiles` (optional, customizable): Installs personal dotfiles so the system is
+  tailored to your workflow.
+* `bin/install_extensions` (optional, customizable): Installs macOS application extensions and
+  add-ons.
+* `bin/install_homebrew_casks` (optional, customizable): Installs Homebrew Formulas.
+* `bin/install_homebrew_formulas` (optional, customizable): Installs Homebrew Casks.
+* `bin/install_node_packages` (optional, customizable): Installs Node packages.
+* `bin/install_ruby_gems` (optional, customizable): Installs Ruby gems.
+* `bin/install_rust_crates` (optional, customizable): Installs Rust crates.
+* `bin/restore_backup` (optional, customizable): Restores system/application settings from backup
+  image.
+* `bin/run` (required): The main script and interface for macOS setup.
+
+The `lib` folder provides the base framework for installing, re-installing, and uninstalling
+software. Everything provided via the link:https://www.alchemists.io/projects/mac_os-config[macOS
+Config] project is built upon the functions found in the `lib` folder. See the
+link:https://www.alchemists.io/projects/mac_os-config[macOS Config] project for further details.
+
+* `lib/settings.sh`: Defines global settings for software applications, extensions, etc.
+
+== Troubleshooting
+
+* *Pi-hole*: When using link:https://pi-hole.net[Pi-hole], you might need to temporarily disable
+  prior to upgrading as you might experience various errors with Apple not being able to detect an
+  internet connection which prevents the installer from working.
+* *Recovery Mode*: When using the boot disk and the installer fails in some catastrophic manner,
+  reboot the machine into recovery mode -- pass:[<kbd>POWER</kbd>] (Silicon) or
+  pass:[<kbd>COMMAND</kbd>] + pass:[<kbd>r</kbd>] (Intel) buttons -- to download and install the
+  last operating system used. Alternatively, you can also use pass:[<kbd>COMMAND</kbd>] +
+  pass:[<kbd>OPTION</kbd>] + pass:[<kbd>r</kbd>] (Intel) to attempt to download the latest operating
+  system.
+* *NVRAM/PRAM Reset*: When using the boot disk, you might experience a situation where you see a
+  black screen with a white circle and diagonal line running through it. This means macOS lost or
+  can't find the boot disk for some reason. To correct this, shut down and boot up the system again
+  while holding down pass:[<kbd>OPTION</kbd>] + pass:[<kbd>COMMAND</kbd>] + pass:[<kbd>r</kbd>] +
+  pass:[<kbd>p</kbd>] (Intel) keys simultaneously. You might want to wait for the system boot sound
+  to happen a few times before releasing the keys. This will clear the system NVRAM/PRAM. At this
+  point you can shut down and restart the system following the boot disk instructions (the boot disk
+  will be recognized now).
+* *System Management Controller (SMC) Reset*: Sometimes it can help to reset the SMC to improve
+  system speed. To fix, follow these steps:
+** Shut down your Mac.
+** Hold down pass:[<kbd>CONTROL</kbd>] + pass:[<kbd>OPTION</kbd>] on the left side of the keyboard
+   and pass:[<kbd>SHIFT</kbd>] on the right side of the keyboard.
+** After seven seconds, hold down the Power button as well.
+** Release all keys after another seven seconds.
+** Turn on your Mac.

-Shell scripts for automated macOS machine setup.
-
-This project is a framework for automating the setup of a macOS machine. In order to illustrate the
-potential of what this project can do, please see the companion
-[macOS Config](https://github.com/bkuhlmann/mac_os-config) project for details. The *macOS Config*
-project is an opinionated configuration which meets the needs of my development environment but is
-also meant to serve as an example and guide for building your own personalized setup. Here is how
-the two projects are meant to be used:
-
-- **macOS** (this project) - Foundation and framework for building customizated macOS machine
-  setups.
-- **[macOS Config](https://github.com/bkuhlmann/mac_os-config)** - The layer on top of this *macOS*
-  project which defines a custom machine setup and base implementation. The project is meant to be
-  forked for as many custom machine setups as needed.

-# Features
-
-- Provides a command line interface, written in Bash with no additional dependencies, for
-  installation and management of a macOS machine.
-- Supports macOS boot disk creation for setting up a machine with a fresh install of the operation
-  system.
-- Downloads and installs development tools (required by Homebrew):
-    - [Xcode Command Line Tools](https://developer.apple.com/xcode)
-    - [Java SE Development Kit](http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html)
-- Downloads, installs, and configures [Homebrew Formulas](http://brew.sh).
-- Downloads, installs, and configures [Homebrew Casks](https://caskroom.github.io).
-- Downloads, installs, and configures
-  [App Store](http://www.apple.com/macosx/whats-new/app-store.html) software.
-- Downloads, installs, and configures non-App Store software applications.
-- Downloads, installs, and configures software application extensions.
-- Applies basic and default software settings.

-# Screencast
-
-[![asciicast](https://asciinema.org/a/88971.png)](https://asciinema.org/a/88971)
-
-# Requirements
-
-0. [macOS Sierra](https://www.apple.com/macos) (with latest software updates applied)
-0. [Xcode](https://developer.apple.com/xcode) (with accepted license agreement)
-
-# Setup
-
-Open a terminal window and execute one of the following setup sequences depending on your version
-preference:
-
-Current Version (stable):
-
-    git clone https://github.com/bkuhlmann/mac_os.git
-    cd mac_os
-    git checkout v2.0.0
-
-Master Version (unstable):
-
-    git clone https://github.com/bkuhlmann/mac_os.git
-    cd mac_os
-
-# Usage
-
-Run the following script:
-
-    bin/run
-
-You will be presented with the following options:
-
-    Boot:
-       B:  Create boot disk.
-    Install:
-       b:  Apply basic settings.
-       t:  Install development tools.
-      hf:  Install Homebrew Formulas.
-      hc:  Install Homebrew Casks.
-       m:  Install Mac App Store software.
-       a:  Install application software.
-       x:  Install application software extensions.
-       d:  Apply default settings.
-       s:  Setup installed software.
-       i:  Install everything (i.e. executes all install options).
-    Restore:
-       R:  Restore settings from backup.
-    Manage:
-       c:  Check status of managed software.
-       C:  Caffeinate machine.
-      ua:  Uninstall application software.
-      ux:  Uninstall application software extension.
-      ra:  Reinstall application software.
-      rx:  Reinstall application software extension.
-       w:  Clean work (temp) directory.
-       q:  Quit/Exit.
-
-Choose option `i` to run all install options or select a specific option to run a single option.
-Each option is designed to be re-run if necessary. This can also be handy for performing upgrades,
-re-running a missing/failed install, etc.
-
-The option prompt can be skipped by passing the desired option directly to the `bin/run` script. For
-example, executing `bin/run i` will execute the complete software install process.
-
-The machine should be rebooted after all install tasks have completed to ensure all settings have
-been loaded.
-
-It is recommended that the `mac_os` project directory not be deleted and kept on the local machine
-in order to manage installed software and benefit from future upgrades.
-
-## Customization
-
-All executable scripts can be found in the `bin` folder:
-
-- `bin/apply_basic_settings`: Applies basic, initial, settings for setting up a machine. *This is
-  meant to be customized.*
-- `bin/apply_default_settings`: Applies useful system and application defaults. *This is meant to be
-  customized.*
-- `bin/create_boot_disk`: Creates macOS boot disk.
-- `bin/install_app_store`: Installs macOS, GUI-based, App Store applications. *This is meant to be
-  customized.*
-- `bin/install_applications`: Installs macOS, GUI-based, non-App Store applications. *This is meant
-  to be customized.*
-- `bin/install_dev_tools`: Installs macOS development tools required by Homebrew.
-- `bin/install_extensions`: Installs macOS application extensions and add-ons. *This is meant to be
-  customized.*
-- `bin/install_homebrew_casks`: Installs Homebrew Formulas. *This is meant to be customized.*
-- `bin/install_homebrew_formulas`: Installs Homebrew Casks. *This is meant to be customized.*
-- `bin/restore_backup`: Restores system/application settings from backup image. *This is meant to be
-  customized.*
-- `bin/run`: The main script and interface for macOS setup.
-- `bin/setup_software`: Configures and launches (if necessary) installed software. *This is meant to
-  be customized.*
-
-The `lib` folder provides the base framework for installing, re-installing, and uninstalling
-software. Everything provided via the [macOS Config](https://github.com/bkuhlmann/mac_os-config)
-project is built upon the functions found in the `lib` folder. See the
-[macOS Config](https://github.com/bkuhlmann/mac_os-config) project for further details.
-
-  - `lib/settings.sh`: Defines global settings for software applications, extensions, etc.
-
