+identity and orientation.
+
+We pledge to act and interact in ways that contribute to an open, welcoming, diverse, inclusive, and

+
+* Demonstrating empathy and kindness toward other people
+* Being respectful of differing opinions, viewpoints, and experiences
+* Giving and gracefully accepting constructive feedback
+* Accepting responsibility and apologizing to those affected by our mistakes, and learning from the
+  experience
+* Focusing on what is best not just for us as individuals, but for the overall community
+
+Examples of unacceptable behavior include:
+
+* The use of sexualized language or imagery, and sexual attention or advances of any kind
+* Trolling, insulting or derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or email address, without their
+  explicit permission
+* Other conduct which could reasonably be considered inappropriate in a professional setting
+
+== Enforcement Responsibilities

+and will take appropriate and fair corrective action in response to any behavior that they deem
+inappropriate, threatening, offensive, or harmful.
+
+Community leaders have the right and responsibility to remove, edit, or reject comments, commits,
+code, wiki edits, issues, and other contributions that are not aligned to this Code of Conduct, and
+will communicate reasons for moderation decisions when appropriate.
+
+== Scope
+
+This Code of Conduct applies within all community spaces, and also applies when an individual is
+officially representing the community in public spaces. Examples of representing our community
+include using an official e-mail address, posting via an official social media account, or acting as
+an appointed representative at an online or offline event.

+**Community Impact**: Use of inappropriate language or other behavior deemed unprofessional or
+unwelcome in the community.
+
+**Consequence**: A private, written warning from community leaders, providing clarity around the
+nature of the violation and an explanation of why the behavior was inappropriate. A public apology
+may be requested.
+
+=== 2. Warning
+
+**Community Impact**: A violation through a single incident or series of actions.
+
+**Consequence**: A warning with consequences for continued behavior. No interaction with the people
+involved, including unsolicited interaction with those enforcing the Code of Conduct, for a
+specified period of time. This includes avoiding interactions in community spaces as well as
+external channels like social media. Violating these terms may lead to a temporary or permanent ban.
+
+=== 3. Temporary Ban
+
+**Community Impact**: A serious violation of community standards, including sustained inappropriate
+behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or public communication with the
+community for a specified period of time. No public or private interaction with the people involved,
+including unsolicited interaction with those enforcing the Code of Conduct, is allowed during this
+period. Violating these terms may lead to a permanent ban.
+
+=== 4. Permanent Ban
+
+**Community Impact**: Demonstrating a pattern of violation of community standards, including
+sustained inappropriate behavior,  harassment of an individual, or aggression toward or
+disparagement of classes of individuals.
+
+**Consequence**: A permanent ban from any sort of public interaction within the community.

+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

+
+== Requirements
+
+. link:https://www.apple.com/macos/big-sur[macOS Big Sur]
+. 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 11.2.0
+----
+
+== 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.
+   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 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`: Applies basic, initial, settings for setting up a machine. _Can be
+  customized._
+* `bin/apply_default_settings`: Applies useful system and application defaults. _Can be customized._
+* `bin/create_boot_disk`: Creates macOS boot disk.
+* `bin/install_app_store`: Installs macOS, GUI-based, App Store applications. _Can be customized._
+* `bin/install_applications`: Installs macOS, GUI-based, non-App Store applications. _Can be
+  customized._
+* `bin/install_dev_tools`: Installs macOS development tools required by Homebrew.
+* `bin/install_extensions`: Installs macOS application extensions and add-ons. _Can be customized._
+* `bin/install_homebrew_casks`: Installs Homebrew Formulas. _Can be customized._
+* `bin/install_homebrew_formulas`: Installs Homebrew Casks. _Can be customized._
+* `bin/restore_backup`: Restores system/application settings from backup image. _Can be customized._
+* `bin/run`: The main script and interface for macOS setup.
+* `bin/setup_software`: Configures and launches (if necessary) installed software. _Can be
+  customized._
+
+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
+
+* 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.
+* When using the boot disk and the installer fails in some catestrophic manner, reboot the machine
+  into recovery mode -- `POWER` (Silicon) or `COMMAND + R` (Intel) buttons -- to download and
+  install the last operating system used. Alternatively, you can also use `COMMAND + OPTION + R`
+  (Intel) to attemp to download the latest operating system.
+* 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
+  the `OPTION + COMMAND + R + P` (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).
+
+== Development
+
+To contribute, run:
+
+[source,bash]

-## Troubleshooting
-
-- 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
-  the `OPTION+COMMAND+R+P` 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).
-- Sometimes, when installing XCode development tools (i.e. the `t` option), not all of the macOS
-  headers will be installed. This can cause issues with compiling and building native packages. For
-  example: `fatal error: 'stdio.h' file not found`. This can happen due to an intermittent bug with
-  the XCode installer. To fix this, you'll need to install this package:
-  `/Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg`. Depending on
-  your system, the version might differ, so look for a `*.pkg` in the
-  `/Library/Developer/CommandLineTools/Packages` folder.
