-The default configuration should suffice. For advanced configuration, you can override the variables documented in the role's [defaults](../roles/custom/matrix-pantalaimon/defaults/main.yml).

 The shortcut commands with the [`just` program](just.md) are also available: `just install-all` or `just setup-all`
 
 `just install-all` is useful for maintaining your setup quickly ([2x-5x faster](../CHANGELOG.md#2x-5x-performance-improvements-in-playbook-runtime) than `just setup-all`) when its components remain unchanged. If you adjust your `vars.yml` to remove other components, you'd need to run `just setup-all`, or these components will still remain installed. Note these shortcuts run the `ensure-matrix-users-created` tag too.

+## Troubleshooting
+
+As with all other services, you can find the logs in [systemd-journald](https://www.freedesktop.org/software/systemd/man/systemd-journald.service.html) by logging in to the server with SSH and running `journalctl -fu matrix-pantalaimon`.
+
+The default logging level for this component is `Warning`. If you want to increase the verbosity, add the following configuration to your `vars.yml` file and re-run the playbook:
+
+```yaml
+# Pantalaimon log level, case-insensitive (Error, Warning, Info, Debug)
+matrix_pantalaimon_log_level: Debug
+```
