# Backstage Plugins
A Backstage Plugin adds functionality to Backstage.
## Create a plugin
To create a new plugin, make sure you've run `yarn install` and installed dependencies, then run the following on your command line (invoking the `backstage-cli`).
```bash
yarn create-plugin
```
This will create a new Backstage Plugin based on the ID that was provided. It will be built and
added to the Backstage App automatically.
_If `yarn start` is already running you should be able to see the default page for your new
plugin directly by navigating to `http://localhost:3000/my-plugin`._
