-### Screen sharing
-
-The screen-sharing-extension-chrome directory includes sample files for developing a
-Chrome extension for enabling screen-sharing for this app. See the
-[OpenTok screen sharing developer guide](https://tokbox.com/developer/guides/screen-sharing/js/)
-for more information.
-
-Follow these steps to use the chrome extension included in this repository.
-
-1. Edit the `manifest.json` file:
-
-   - Set the `matches` property to match only your web domains. (When developing in
-     the localhost environment, you can use `"matches": ["http://localhost/*"]`).
-
-   - Change the `name` and `author` settings
-
-   - Replace the icon files (logo16.png, logo48.png, logo128.png, and logo128transparent.png)
-     with your own website logos.
-
-   - Change the `version` setting with each new version of your extension.
-
-   - You may want to change the `description`.
-
-   For more information, see the [Chrome extension manifest
-   documentation](https://developer.chrome.com/extensions/manifest).
-
-2. Load the extension into Chrome:
-
-   Open [chrome://extensions](chrome://extensions) and drag the screen-sharing-extension-chrome
-   directory onto the page, or click 'Load unpacked extension...'. For more information see
-   [Chrome's documentation on loading unpacked
-   extensions](https://developer.chrome.com/extensions/getstarted#unpacked).
-
-3. Add the `extensionId` to application configuration:
-
-   You can get the ID of the extension in the [chrome://extensions](chrome://extensions) page.
-   (It looks like `ffngmcfincpecmcgfdpacbdbdlfeeokh`).
-   Add the value to the configuration, see [Configuration Options: Screen sharing](#screen-sharing).
