+## Etherpad support
+
+Thanks to [@pushytoxin](https://github.com/pushytoxin), the playbook can now install the [Etherpad](https://etherpad.org) realtime collaborative text editor. It can be used in a [Jitsi](https://jitsi.org/) audio/video call or integrated as a widget into Matrix chat rooms via the [Dimension](https://dimension.t2bot.io) integration manager.
+
+To get it installed, follow [our Etherpad docs page](docs/configuring-playbook-etherpad.md).

+# Setting up Etherpad (optional)
+
+[Etherpad](https://etherpad.org) is is an open source collaborative text editor that can be embedded in a Matrix chat room using the [Dimension integrations manager](https://dimension.t2bot.io)
+
+When enabled together with the Jitsi audio/video conferencing system (see [our docs on Jitsi](configuring-playbook-jitsi.md)), it will be made available as an option during the conferences.
+
+## Prerequisites
+
+For the self-hosted Etherpad instance to be available to your users, you must first enable and configure the **Dimension integrations manager** as described in [the playbook documentation](configuring-playbook-dimension.md)
+
+## Installing
+
+[Etherpad](https://etherpad.org) installation is disabled by default. You can enable it in your configuration file (`inventory/host_vars/matrix.<your-domain>/vars.yml`):
+
+```yaml
+matrix_etherpad_enabled: true
+```
+
+## Set Dimension default to the self-hosted Etherpad
+
+The Dimension administrator users can configure the default URL template. The Dimension configuration menu can be accessed with the sprocket icon as you begin to add a widget to a room in Element. There you will find the Etherpad Widget Configuration action beneath the _Widgets_ tab. Replace `scalar.vector.im` with your own Dimension domain.
+
+### Removing the integrated Etherpad chat
+
+If you wish to disable the Etherpad chat button, you can do it by appending `?showChat=false` to the end of the pad URL, or the template.
+Example: `https://dimension.<your-domain>/etherpad/p/$roomId_$padName?showChat=false`
