+# Setting up MX Puppet Slack (optional)
+
+The playbook can install and configure
+[mx-puppet-slack](https://github.com/Sorunome/mx-puppet-slack) for you.
+
+See the project page to learn what it does and why it might be useful to you.
+
+To enable the [Slack](https://www.slack.com/) bridge just use the following
+playbook configuration:
+
+
+```yaml
+matrix_mx_puppet_slack_enabled: true
+matrix_mx_puppet_slack_client_id: ""
+matrix_mx_puppet_slack_client_secret: ""
+```
+
+
+## Usage
+
+Once the bot is enabled you need to start a chat with `Slack Puppet Bridge` with
+the handle `@_slackpuppet_bot:YOUR_DOMAIN` (where `YOUR_DOMAIN` is your base
+domain, not the `matrix.` domain).
+
+Three authentication methods are available, Legacy Token, OAuth and xoxc token.
+See mx-puppet-slack [documentation](https://github.com/Sorunome/mx-puppet-slack)
+for more information about how to configure the bridge.
+
+Once logged in, send `list` to the bot user to list the available rooms.
+
+Clicking rooms in the list will result in you receiving an invitation to the
+bridged room.
+
+Also send `help` to the bot to see the commands available.
