 # Dotify
 
+Setup your dotfiles like a sane person. With a Dotfile ^_^
+
+```bash
+ackrc     -> .ackrc
+gitconfig -> .gitconfig
+tmux.conf -> .tmux.conf
+
+if [ "$(uname)" == "Darwin" ]; then
+  powconfig -> .powconfig
+fi
+```
+
+## Overview
+
+### Setup
+
+Let's say you've got a git repo somewhere in which you keep your dotfiles.
+And lets say that repo looks something like this:
+
+```
+.
+|-- dotify
+|-- Dotfile
+|-- hosts
+|   `-- mordor
+|       |-- Dotfile
+|       `-- gitconfig
+|-- irbrc
+`-- tmux.conf
+```
+
+The `dotify` file is Dotify's main executable, which is a small self-contained
+bash script. It doesn't need to be included in your dotfiles, but it doesn't
+hurt.
+
+The `Dotfile` in the root looks like this:
+
+```bash
+irbrc     -> .irbrc
+tmux.conf -> .tmux.conf
+
+if [ -f "hosts/$(hostname)/Dotfile" ]; then
+  include "hosts/$(hostname)"
+fi
+```
+
+And `hosts/mordor/Dotfile` like this:
+
+```bash
+gitconfig -> .gitconfig
+```
+
+### Running
+
+Now let's say your machine's hostname is `mordor`, and you've cloned your
+dotfiles repo to `~/src/dotfiles`. If you were to cd into your dotfiles and
+run `./dotify install`, you'll end up with a home folder like this:
+
+```
+.
+|-- .dotfiles -> /home/jimeh/src/dotfiles
+|-- .gitconfig -> .dotfiles/gitconfig
+|-- .irbrc -> .dotfiles/irbrc
+|-- .tmux.conf -> .dotfiles/tmux.conf
+`-- src
+```
