+Run the netsoak ServerLauncher with the relevant comand line values, using the format is ```--<command>=<value>```. See the full list of options below.
 
+For example, the following params will run the loopback test for 2 minutes before dumping stats and exiting:
 ``` 
-NetSoakTest.ServerLauncher --soak_mode=loopback 
+NetSoakTest.ServerLauncher --soak_mode=loopback --soak_runtime=2000
 ```
 
-When running tests, you can use the [debug console](https://www.o3de.org/docs/user-guide/appendix/cvars/debugging/#using-console-debug-views) and the `DumpSoakStats` command to see point-in-time stats from the test. The test will run indefinitely until such point it is terminated.
