 ## Example: How to start pods at 2pm and stop them at 3pm every day
 The following example start `5` replicas in total at `2pm` and stop `4` of them at `3pm` every day, the deployment start with `0` replicas.
 
-The `start-replicas` is not incremental, the value is the number of replicas will be setup by Another Scheduler at the defined time by `start-time`.
