 In the world of the Matrix chat protocol, there are various client programs.

 This configuration **disables SSL certificate retrieval**, so you will **need to obtain SSL certificates manually** (e.g. by using [certbot](https://certbot.eff.org/)) and set the appropriate path in `matrix.conf`. In the example nginx configuration, a single certificate is used for all subdomains (`matrix.DOMAIN`, `element.DOMAIN`, etc.). For your setup, may wish to change this and use separate `server` blocks and separate certificate files for each host.
 
-Also note that your copy of the `matrix.conf` file has to be adapted to whatever services you are using. For example, remove `element.domain.com` from the `server_name` list if you don't use [Element](../../../docs/configuring-playbook-client-element.md) web client or add `dimension.domain.com` to it if you do use the [Dimension](../../../docs/configuring-playbook-dimension.md) integration manager.
