Merge pull request denisidoro#101 from alxbl/omzsh-plugin

Thanks for making this project, it's really cool! I'd been looking for something like this for a while.
I noticed that your shell widget is pretty much stand-alone and I wanted to be able to use navi directly as an [oh-my-zsh][1] plugin, so I added a few things to the widget and moved it to the root of the repository so that the repo can be cloned straight into the `plugins` folder and detected when added in the plugin array.

I think it should be similarly simple with `fish`, but I'm not too familiar with that shell, so I'll leave it to someone else. The `navi.plugin.zsh` file should still be sourcable as a widget for people not using oh-my-zsh, so technically the `shell/` directory could be removed and `navi widget`updated to use the new file.

## What's included
- oh-my-zsh plugin
- install documentation
- no PATH modification required when used with OMZ
- Added bonus: denisidoro#51 is kind of unofficially addressed by this (assuming one uses OMZ)

## Future Work
- Pre-filter using `$BUFFER` when hitting `Alt+G` to get something similar to `navi query`
- Update `navi widget zsh` to use `navi.plugin.zsh`

Let me know what you think. I'm working on a few cheatsheets, and will open PRs for those as they become ready.

Cheers,
Alex

 Alternatively, you can `git clone` this repository and run `make`:
 
 ```sh
-git clone --depth 1 http://github.com/denisidoro/navi /opt/navi
+git clone --depth 1 https://github.com/denisidoro/navi /opt/navi
 cd /opt/navi
 sudo make install
 # install fzf: https://github.com/junegunn/fzf
 ```
 
+
+### Using oh-my-zsh
+
+Make sure that your oh-my-zsh `$ZSH_CUSTOM` directory is configured, then clone navi into the plugins directory.
+```sh
+export ZSH_CUSTOM='/path/to/.zsh'
+plugins_dir="$ZSH_CUSTOM/plugins"
+mkdir -p "$plugins_dir"
+cd "$plugins_dir"
+git clone https://github.com/denisidoro/navi
+```
+
+Then, add it to the oh-my-zsh plugin array:
+```
+# Sample ~/.zshrc
+ZSHCFG="$HOME/.zsh"
+ZSH="$ZSHCFG/oh-my-zsh"
+ZSH_CUSTOM="$ZSHCFG"
+plugins=(docker tmux fzf navi)
+# ...
+source "$ZSH/oh-my-zsh.sh"
+```
+
+Finally, you can use it as a [shell widget](#shell-widget).
+
+This method has the advantage of not requiring root to install and disadvantage of not allowing you to invoke the script by calling `navi` (unless you add an alias to it or copy it to a folder in `$PATH`).
