 The Provider plugins help you connect to your accounts with remote file providers such as [Dropbox](https://dropbox.com), [Google Drive](https://drive.google.com), [Instagram](https://instagram.com) and remote URLs (importing a file by pasting a direct link to it). Because this requires server-to-server communication, they work tightly with [Companion](https://github.com/transloadit/uppy/tree/master/packages/%40uppy/companion) to manage the server-to-server authorization for your account. Almost all of the communication (file download/upload) is done on the server-to-server end, so this saves you the stress and bills of data consumption on the client.
 
-As of now, the supported providers are [**Dropbox**](/docs/dropbox), [**GoogleDrive**](/docs/google-drive), [**Instagram**](/docs/instagram), and [**URL**](/docs/url).

 Usage of the Provider plugins is not that different from any other *acquirer* plugin, except that it takes an extra option `companionUrl`, which specifies the URL to the Companion that you are running. This allows Uppy to know what server to connect to when datacenter operations are required by the provider plugin.
