 Probot uses [GitHub Apps](https://developer.github.com/apps/). An app is a first-class actor on GitHub, like a user (e.g. [@defunkt](https://github.com/defunkt)) or an organization (e.g. [@github](https://github.com/github)). The app is given access to a repository or repositories by being "installed" on a user or organization account and can perform actions through the API like [commenting on an issue](https://developer.github.com/v3/issues/comments/#create-a-comment) or [creating a status](https://developer.github.com/v3/repos/statuses/#create-a-status).

It is an instance of the [github Node.js module](https://github.com/octokit/node-github), which wraps the [GitHub REST API](https://developer.github.com/v3/) and allows you to do almost anything programmatically that you can do through a web browser.

 If your Probot App needs to store more data than Issues and Pull Requests store normally, you can use the [`probot-metadata` extension](https://probot.github.io/docs/extensions/#metadata) to hide data in comments. It isn't meant to be super secure or scalable, but it's an easy way to manage some data without a full database.
