+#### Configuring Google Drive file uploads

+An alternative to S3 file storage is Google Drive file storage, which offers up to 15GB of free storage. To configure Google Drive storage, specify the following environment variables during app deployment, or in the app settings after the app is deployed.
+- `GOOGLE_PRIVATE_KEY_ID`, `GOOGLE_PRIVATE_KEY`, `GOOGLE_CLIENT_EMAIL`, and `GOOGLE_CLIENT_ID`.
+Instructions on how to obtain these variables can be found in the [ghost-google-drive](https://github.com/robincsamuel/ghost-google-drive) driver repository.

 This repository is a [Node.js](https://nodejs.org) web application that specifies [Ghost as a dependency](https://docs.ghost.org/v1.0.0/docs/using-ghost-as-an-npm-module), and makes a deploy button available.
