-## powerlevel9k Theme for Oh-My-Zsh
+## powerlevel9k Theme for ZSH
 
-This is a theme for [Oh-My-Zsh](https://github.com/robbyrussell/oh-my-zsh). This
-theme uses [Powerline Fonts](https://github.com/Lokaltog/powerline-fonts), thus
-giving you the most epic terminal styling in the universe.
+Powerlevel9k is a theme for ZSH which uses [Powerline
+Fonts](https://github.com/Lokaltog/powerline-fonts). It can be used with vanilla
+ZSH, [Oh-My-Zsh](https://github.com/robbyrussell/oh-my-zsh), or
+[Prezto](https://github.com/sorin-ionescu/prezto), and can also be installed
+using [antigen](https://github.com/zsh-users/antigen).
 
 Look like a bad-ass. Impress everyone in 'Screenshot Your Desktop' threads. Use powerlevel9k.
 
-In addition to looking amazing, this theme actually provides a lot of useful
-information in configurable prompt segments.
+![](http://bhilburn.org/content/images/2015/01/pl9k-improved.png)
+
+There are a number of Powerline ZSH themes available, now. The developers of
+this theme focus on three primary goals:
+
+1. Give users a great out-of-the-box configuration with no additional
+   configuration required.
+2. Make customization easy for users who do want to tweak their prompt.
+3. Provide useful segments that you can enable to make your prompt even more
+   effective and helpful. We have prompt segments for everything from unit test
+   coverage to your AWS instance.

 ### Installation
+There are two steps to start using this theme:
 
-There are two things you need to make this theme work correctly: Powerline
-fonts, and the theme itself.
+1. Install the Powerlevel9k theme.
+2. Install Powerline-patched fonts.
+3. [Optional] Configuration
 
-#### Install Powerline Fonts
-First, you need to install Powerline Fonts. You can find the [installation
-instructions
-here](https://powerline.readthedocs.org/en/latest/installation/linux.html#fonts-installation).
-You can also find the raw font files [in this Github
-repository](https://github.com/powerline/fonts) if you want to manually install
-them for your OS.
+To get the most out of Powerlevel9k, you need to install both the theme as well
+as Powerline-patched fonts, if you don't have them installed already. If you
+cannot install Powerline-patched fonts for some reason, follow the instructions
+below for a `compatible` install.
 
-After you have installed Powerline fonts, make the default font in your terminal
-emulator the Powerline font you want to use.
+No configuration is necessary post-installation if you like the default
+settings, but there is plenty of segment configuration available if you are
+interested.
 
-#### Install Powerlevel9k
+#### Step 1: Install Powerlevel9k
+There are four ways to install and use the Powerlevel9k theme: vanilla ZSH,
+Oh-My-Zsh, Prezto, and antigen. Do one of the following:
 
-To install this theme, clone this repository into your Oh-My-Zsh `custom/themes`
-directory.
+##### Option 1: Install for Vanilla ZSH
+
+If you use just a vanilla ZSH install, simply clone this repository and
+reference it in your `~/.zshrc`:
+
+    $ git clone https://github.com/bhilburn/powerlevel9k.git
+    $ echo 'source  powerlevel9k/powerlevel9k.zsh-theme' >> ~/.zshrc
+
+##### Option 2: Install for Oh-My-ZSH
+
+To install this theme for
+[Oh-My-Zsh](https://github.com/robbyrussell/oh-my-zsh), clone this repository
+into your OMZ `custom/themes` directory.
 
     $ cd ~/.oh-my-zsh/custom
     $ git clone https://github.com/bhilburn/powerlevel9k.git themes/powerlevel9k
@@ -66,6 +125,99 @@ You then need to select this theme in your `~/.zshrc`:
 
     ZSH_THEME="powerlevel9k/powerlevel9k"
 
+##### Option 3: Install for Prezto
+
+To install this theme for use in Prezto, clone this repository into your
+[Prezto](https://github.com/sorin-ionescu/prezto) `prompt/external` directory.
+
+    $ cd ~.zprezto/modules/prompt/external
+    $ git clone https://github.com/bhilburn/powerlevel9k.git
+    $ ln -s powerlevel9k/powerlevel9k.zsh-theme ../functions/prompt_powerlevel9k_setup
+
+You then need to select this theme in your `~/.zpreztorc`:
+
+    zstyle ':prezto:module:prompt' theme 'powerlevel9k'
+
+##### Option 4: Install for antigen
+
+If you prefer [antigen](https://github.com/zsh-users/antigen), just add this
+theme to the antigen config in your `~/.zshrc`:
+
+    $ echo 'antigen theme bhilburn/powerlevel9k powerlevel9k' >> ~/.zshrc
+    $ echo 'antigen apply' >> ~/.zshrc
+
+Note that you should define any customizations before calling `antigen theme`
+(i.e. setting the `POWERLEVEL9K_*` variables) in your `.zshrc`.
+
+#### Step 2: Install Powerline Fonts
+Technically, you don't *have* to install Powerline fonts. If you are using
+a font that has some of the basic glyphs we need, you can use the theme in
+`compatible` mode - see the third option, below.
+
+To get the most out of theme, though, you'll want Powerline-patched fonts. There
+are two varieties of these: 'Powerline Fonts' and 'Awesome Powerline
+Fonts'. The latter includes additional glyphs that aren't required for a normal
+install.
+
+Do one of the following:
+
+##### Option 1: Install Powerline Fonts
+
+You can find the [installation instructions for Powerline Fonts here]
+(https://powerline.readthedocs.org/en/latest/installation/linux.html#fonts-installation).
+You can also find the raw font files [in this Github
+repository](https://github.com/powerline/fonts) if you want to manually install
+them for your OS.
+
+After you have installed Powerline fonts, make the default font in your terminal
+emulator the Powerline font you want to use.
+
+This is the default mode for `Powerlevel9k`, and no further configuration is
+necessary.
+
+**N.B.:** If Powerlevel9k is not working properly, it is almost always the case
+that the fonts were not properly installed, or you have not configured your
+terminal to use a Powerline-patched font!
+
+##### Option 2: Install Awesome Powerline Fonts
+
+Alternatively, you can install [Awesome Powerline
+Fonts](https://github.com/gabrielelana/awesome-terminal-fonts), which provide
+a number of additional glyphs.
+
+You then need to indicate that you wish to use the additional glyphs by defining
+the following in your `~/.zshrc`:
+
+    POWERLEVEL9K_MODE='awesome-patched'
+
+If you choose to make use of this, your prompt will look something like this:
+
+![](https://cloud.githubusercontent.com/assets/1544760/7959660/67612918-09fb-11e5-9ef2-2308363c3c51.png)
+
+Note that if you prefer flat segment transitions, you can use the following with
+`Awesome Powerline Fonts` installed:
+
+    POWERLEVEL9K_MODE='flat'
+
+Which looks like this:
+
+![](https://cloud.githubusercontent.com/assets/1544760/7981324/76d0eb5a-0aae-11e5-9608-d662123d0b0a.png)
+
+##### Option 3: Compatible Mode
+
+This option is best if you prefer not to install additional fonts. This option
+will work out-of-the-box if your your terminal font supports the segment
+separator characters `\uE0B0` (left segment separator) and `\uE0B2` (right
+segment separator).
+
+All you need to do to in this case is install the `Powerlevel9k` theme itself,
+as explained above, and then define the following in your `~/.zshrc`:
+
+    POWERLEVEL9K_MODE='compatible'
+
+Note that depending on your terminal font, this may still not render
+appropriately. This configuration should be used as a back-up.

+# Test-VM for powerlevel9k
+
+In this virtual machine you will find a recent ubuntu with preinstalled ZSH, oh-my-zsh, antigen, prezto and - of course - powerlevel9k. The main use-case is to test the powerlevel9k theme.
+
+## Installation
+
+In order to run this virtual machine, you need [vagrant](https://www.vagrantup.com/) and [VirtualBox](http://www.virtualbox.org/).
+
+## Running
+
+`vagrant` is a quite easy to use command line tool to configure a virtual machine. To fire the machine up, just run `vagrant up`. At the first run, it will install a whole ubuntu. With `vagrant ssh` you can log in into the machine.
+
+## Testing
+
+Once you have SSH'd into the machine, you'll see a plain ZSH. To test the other frameworks, you just have to switch to one of the following users:
+
+  * `vagrant-antigen`
+  * `vagrant-prezto`
+  * `vagrant-omz`
+
+To switch use `sudo -i -H -u <USERNAME>`. `-i` stands for "simulate initial login", `-H` sets the "$HOME" variable to the directory of the user , `-u` for the username. 
+
+All users have `vagrant` as password and are in the /etc/sudoers.
+
+The regular `vagrant` user has a plain ZSH with the powerlevel9k theme.
