 This feature is demonstrated in the above Helm install command. Running a `helm update ...` with changes to the `zilla.yaml`, k8s will update the config map, which writes the new content into the running pods. Zilla will detect those file changes and load the new config.
 
+Zilla can load the `zilla.yaml` config from a remote source using the `-c` or `--config` [CLI flag](../reference/config/zilla-cli.md#c-config). The auto reconfigure feature will still work when pulling the config remotely.

 ## Auto Scaling
 
 Zilla will start workers that default to the CPU cores it is allowed to use. This makes horizontal scaling easy with a 1:1 ratio of instances to workers. Any of the default scaling metrics based on server CPU usage will enable Zilla to handle traffic spikes. Additionally, Zilla [Telemetry](../reference/config/overview.md#telemetry) configuration provides more data when determining how to scale. The [Prometheus autoscale example](https://github.com/aklivity/zilla-examples/tree/main/kubernetes.prometheus.autoscale) demonstrates using metrics from the [Prometheus exporter](../reference/config/telemetry/exporters/prometheus.md) to horizontally scale Zilla on k8s.
