# Plugins
Dokku itself is built out of plugins and uses [pluginhook ](https://github.com/progrium/pluginhook ) for its plugin system. In essence a plugin is a collection of scripts that will be run based on naming convention.
Let's take a quick look at the current dokku nginx plugin that's shipped with dokku by default.
nginx-vhosts/
├── commands # contains additional commands
├── install # runs on dokku installation
└── post-deploy # runs after an app is deployed
## Installing a plugin
2014-12-19 15:09:38 -05:00
```shell
2014-10-04 04:24:22 -04:00
cd /var/lib/dokku/plugins
git clone <git url>
dokku plugins-install
```
> todo: add a command to dokku to install a plugin, given a git repository `dokku plugin:install <git url>`?
