 The provisioning API will be enabled automatically if you set `matrix_dimension_enabled: true` and provided a `matrix_hookshot_provisioning_secret`, unless you override it either way. To use hookshot with dimension, you will need to enter as "Provisioning URL": `http://matrix-hookshot:9002`, which is made up of the variables `matrix_hookshot_container_url` and `matrix_hookshot_provisioning_port`.
 
-If metrics are enabled, they will be automatically available in the builtin Prometheus and Grafana, but you need to set up your own Dashboard for now. If additionally metrics proxying for use with external Prometheus is enabled (`matrix_nginx_proxy_proxy_synapse_metrics`), hookshot metrics will also be available (at `matrix_hookshot_metrics_endpoint`, default `/hookshot/metrics`, on the stats subdomain). See also [the Prometheus and Grafana docs](../configuring-playbook-prometheus-grafana.md).

If additionally metrics proxying for use with external Prometheus is enabled (`matrix_nginx_proxy_proxy_synapse_metrics`), hookshot metrics will also be available (at `matrix_hookshot_metrics_endpoint`, default `/hookshot/metrics`, on the stats subdomain) and with the same password. See also [the Prometheus and Grafana docs](../configuring-playbook-prometheus-grafana.md).
 
 Other configuration options are available via the `matrix_hookshot_configuration_extension_yaml` and `matrix_hookshot_registration_extension_yaml` variables, see the comments in `/roles/matrix-bridge-hookshot/defaults/main.yml` for how to use them.
