Ability to store your own prompts in ~/.zsh.prompts [Close #152]

We no longer pollute yadr or prezto directories with custom code!

 For a more complete Zsh experience we use **[Prezto](http://github.com/sorin-ionescu/prezto)**. 
 Prezto is included as a submodule.
 
+### Adding your own ZSH theme
+
+If you want to add your own zsh theme, you can place it into ~/.zsh.prompts and it will automatically be picked up by the prompt loader.
+
+Make sure you follow the naming convention of `prompt_[name]_setup`
+
+```
+touch ~/.zsh.prompts/prompt_mytheme_setup
+```
+
+Check out ~/.yadr/zsh/prezto-themes/prompt_skwp_setup for an example of how to write a prompt.
+See also the [Prezto](https://github.com/sorin-ionescu/prezto) project for more info on themes.
+
+### Customizing ZSH & Picking a theme
+
 If you want to customize your zsh experience, yadr provides two hooks via ~/.zsh.after/ and ~/.zsh.before/ directories.
 In these directories, you can place files to customize things that load before and after other zsh customizations that come from ~/.yadr/zsh/*
 
 For example, to override the theme, you can do something like this:
 ```
-mkdir ~/.zsh.after
 echo "prompt skwp" > ~/.zsh.after/prompt.zsh
 ```
