-### Hosting your app with Glitch
-
-You can see an [example Probot app](https://glitch.com/~auspicious-aardwolf) that uses [Glitch](https://glitch.com/) to host and share the app. The example uses the [Checks API](/rest/checks) and selects the necessary Checks API events and permissions in the `app.yml` file. Glitch is a tool that allows you to "Remix your own" apps. Remixing an app creates a copy of the app that Glitch hosts and deploys. See [About Glitch](https://glitch.com/about/) to learn about remixing Glitch apps.
