+# Setting up Go Skype Bridge (optional)
+
+The playbook can install and configure
+[go-skype-bridge](https://github.com/Sorunome/go-skype-bridge) for you.
+
+See the project page to learn what it does and why it might be useful to you.
+
+To enable the [Skype](https://www.skype.com/) bridge just use the following
+playbook configuration:
+
+
+```yaml
+matrix_go_skype_bridge_enabled: true
+```
+
+
+## Usage
+
+Once the bot is enabled, you need to start a chat with `Skype Puppet Bridge`
+with the handle `@skypebridgebot:YOUR_DOMAIN` (where `YOUR_DOMAIN` is your base
+domain, not the `matrix.` domain).
+
+Send `help` to the bot to see the commands available.
