+#### Suspending and resuming a specific cron task
+
+Cron tasks can be suspended to temporarily prevent them from running, and later resumed to re-enable them. This is useful for maintenance or debugging purposes.
+
+To suspend a specific cron task, use the `cron:suspend` command with the app name and cron ID:
+
+```shell
+dokku cron:suspend node-js-app cGhwPT09cGhwIHRlc3QucGhwPT09QGRhaWx5
+```
+
+A suspended task will not execute according to its schedule. You can verify a task is suspended by checking the `Maintenance` column in the `cron:list` output, which will show `true (task)` for suspended tasks.
+
+To resume a suspended cron task, use the `cron:resume` command:
+
+```shell
+dokku cron:resume node-js-app cGhwPT09cGhwIHRlc3QucGhwPT09QGRhaWx5
+```
+
+Once resumed, the task will execute according to its schedule again. The cron ID can be retrieved from the `cron:list` output.
+
 #### Executing a cron task on the fly
 
 Cron tasks can be invoked via the `cron:run` command. This command takes an `app` argument and a `cron id` (retrievable from `cron:list` output).
