+## Rafiki-zsh
+
+Rafiki-zsh is a [oh-my-zsh](https://github.com/robbyrussell/oh-my-zsh) theme that adds emojis to your zsh terminal.
+Rafiki will display a `good` emoji such as :smile: on your prompt whenever commands run smoothly and `bad` emojis
+such as :rage: whenever things go wrong.
+
+### Setup
+
+To set up the theme. Ensure that you have [oh-my-zsh](https://github.com/robbyrussell/oh-my-zsh) installed and setup on your terminal.
+
+Clone the repo or download `rafiki.zsh-theme` file.
+
+    $ git clone https://github.com/akabiru/rafiki-zsh
+
+
+Copy `rafiki.zsh-theme` to `~/.oh-my-zsh/custom/themes/`. This is where your custom themes live.
+
+    $ cp /path/to/rafiki.zsh-theme ~/.oh-my-zsh/custom/themes/
+
+Change your zsh theme to rafiki in your `.zshrc` file.
+
+    $ vim ~/.zshrc
+
+    ZSH_THEME='rafiki'
+
+Restart your terminal and Voila! Rafiki is watching over you.
+
+### Usage
+
+Rafiki generates random emojis every time you start up your terminal. It also tells you who your pals are for the session.
+
+To generate a new set just run `newrafiki`
+
+    $ newrafiki
+
+You can also run `rafiki` to remind yourself your emoji set.
+
+    $ rafiki
+
+### Customization
+
+Rafiki is pretty customizable.
+
+If you prefer to have a constant set of emojis just set your `good`emoji and `bad` emoji in `.zshrc` as follows.
+
+For good emojis, set `$MY_GOOD_RAFIKI` to one of the following: `fire muscle pointright facepunch smile sunglasses` and
+your `bad` emoji to one of the following: `rollingeyes pouting confused flushed middlefinger worried`
+
+    $MY_GOOD_RAFIKI='fire'
+    $MY_BAD_RAFIKI='rollingeyes'
+
+Then reload your zsh configuration.
+
+    $ source ~/.zshrc
+
+You can also add your own emojis to the supported set. Just add the emoji name to one of the arrays; `goodemojis` or `bademojis`.
+Then add the emoji to the respective array with the name as the key and the emoji as the value.
+
+### Contributing
+
+Feel free to contribute, even if it's to add an emoji. :wink: Just fork it :fork_and_knife: and raise a pull request.
+
+### Credits
+
+This projects borrows from [Robby Russell's](https://github.com/robbyrussell/oh-my-zsh/blob/master/themes/robbyrussell.zsh-theme) theme.
+Not forgetting [oh-my-zsh](https://github.com/robbyrussell/oh-my-zsh) itself. :smile:
