 The `element.example.com` subdomain may be necessary, because this playbook installs the [Element Web](https://github.com/element-hq/element-web) client for you. If you'd rather instruct the playbook not to install Element Web (`matrix_client_element_enabled: false` when [Configuring the playbook](configuring-playbook.md) later), feel free to skip the `element.example.com` DNS record.
 
-The `dimension.example.com` subdomain may be necessary, because this playbook could install the [Dimension integration manager](http://dimension.t2bot.io/) for you.

If you do not wish to set up Dimension, feel free to skip the `dimension.example.com` DNS record.
