 # Usage
 
@@ -130,10 +129,6 @@ For example, to run without auth, use the following config:
 * `--prometheus-address`: The address to bind the Prometheus scrape endpoint, default to `127.0.0.1`.
 * `--prometheus-port`: The port to bind the Prometheus scrape endpoint, default to 20257. Use 0 to disable.
 
-#### For Stackdriver exporter
-
-* `--exporter.stackdriver`: Path to a Stackdriver exporter config file, e.g. [config/exporter/stackdriver-exporter.json](https://github.com/kubernetes/node-problem-detector/blob/master/config/exporter/stackdriver-exporter.json), defaults to empty string. Set to empty string to disable.
-
 ### Deprecated Flags
 
 * `--system-log-monitors`: List of paths to system log monitor config files, comma-separated. This option is deprecated, replaced by `--config.system-log-monitor`, and will be removed. NPD will panic if both `--system-log-monitors` and `--config.system-log-monitor` are set.
