+# About
+This repository contains everything needed to bootstrap and configure new Mac computer. Included here are:
+
+  * dotfiles
+  * ~/bin/ scripts
+  * Configuration files
+  * Scripting templates and utilities
+  * `install.sh`, a script to put everything where it needs to go
+
+**Disclaimer:**  *I am not a professional programmer and I bear no responsibility whatsoever if any of these scripts wipes your computer, destroys your data, crashes your car, or otherwise causes mayhem and destruction.  USE AT YOUR OWN RISK.*
+
+## install.sh
+This script runs through a series of tasks to configure a new computer. There are three distinct areas of `install.sh` which are executed in order.  These are:
+
+  1. **Bootstrapping** - Installing base components such as Command Line Tools, Homebrew, Node, RVM, etc.
+  2. **Installation** - Symlinking dotfiles and installing executables such as NPM Packages, Homebrew Casks, etc.
+  3. **Configuration** - Configures installed packages and apps.
+
+The files are organized into three subdirectories.
+
+```
+dotfiles
+├── bin/
+├── config/
+│   ├── bash/
+│   └── shell/
+├── install.sh
+├── install-config.yaml
+├── lib/
+│   ├── bootstrap/
+│   └── configure/
+└── scripting/
+```
+
+  * **bin** - Symlinked to `~/bin` and is added to your `$PATH`.
+  * **config** - Contains the elements needed to configure your environment and specific apps.
+  * config/**bash** - Files in this directory are *sourced* by `.bash_profile`.
+  * config/**shell** - Files here are symlinked to your local environment. Ahem, dotfiles.
+  * **lib** - Contains the scripts and configuration for `install.sh`
+  * lib/**bootstrap** - Scripts here are executed by `install.sh` first.
+  * lib/**configure** - Scripts here are exectuted by `install.sh` after packages have been installed
+  * **config-install.yaml** - This YAML file contains the list of symlinks to be created, as well as the packages to be installed.
+  * **scripting** - This directory contains bash scripting utilities and templates which I re-use often.
+
+**IMPORTANT:** Unless you want to use my defaults, make sure you do the following:
+
+  * Edit `config-install.yaml` to reflect your preferred packages
+  * Review the files in `config/` to configure your own aliases, preferences, etc.
+
+#### Private Files
+
+Sometimes there are files which contain private information. These might be API keys, local directory structures, or anything else you want to keep hidden.
+
+Private files are held in a separate folder named `private`. This repository is added as a git-submodule and files within it are symlinked to `$HOME` or sourced to the Bash terminal.
+
+Since you're not me, you should **fork this repository and replace the `private` directory with a git submodule of your own.**
+
+Within the private directory you can write your own install script to configure and install your own files.  This script should be named: `privateInstall.sh`
+
+If `private/privateInstall.sh` exists, `install.sh` will invoke it.
+
+## Cloning this repo to a new computer
+The first step needed to use these dotfiles is to clone this repo into the $HOME directory.  To make this easy, I created [a gist](https://gist.github.com/natelandau/b6ec165862277f3a7a4beff76da53a9c) which can easily be run with the following command:
+
+```
+curl -SL https://gist.githubusercontent.com/natelandau/b3e1dfba7491137f0a0f5e25721fffc2/raw/d98763695a0ddef1de9db2383f43149005423f20/bootstrapNewMac | bash
+```
+
+This gist creates a script `~/bootstrap.sh` in your home directory which completes the following tasks
+
+  1. Creates a new public SSH key if needed
+  2. Copies your public key to your clipboard
+  3. Opens Github to allow you to add this public key to your 'known keys'
+  4. Clones this dotfiles repo to your home directory
+
+See. Easy. Now you're ready to run `~/dotfiles/install.sh` and get your new computer working.
+
+### A Note on Code Reuse
+Many of the scripts, configuration files, and other information herein were created by me over many years without ever having the intention to make them public. As a novice programmer, I have Googled, GitHubbed, and StackExchanged a path to solve my own scripting needs.  Quite often I would lift a function whole-cloth from a GitHub repo and not keep track of it's original location.  I have done my best within these files to recreate my footsteps and give credit to the original creators of the code when possible.  Unfortunately, I fear that I missed as many as I found.  My goal of making this repository public is not to take credit for the wonderful code written by others. If you recognize or wrote something here that I didn't credit, please let me know.
