+## Isolating Action Execution
+
+If you are deploying your application across multiple servers and running migrations as part of your deployment process, you likely do not want two servers attempting to migrate
+the database at the same time. To avoid this, you may use the `isolated` option when invoking the `migrate:actions` command.
+
+When the `isolated` option is provided, Laravel will acquire an atomic lock using your application's cache driver before attempting to run your migrations. All other attempts to
+run the `migrate:actions` command while that lock is held will not execute; however, the command will still exit with a successful exit status code:
+
+```bash
+php artisan migrate:actions --isolated
+```
+
 ## Split Launch Option
 
 Sometimes it becomes necessary to launch actions separately, for example, to notify about the successful deployment of a project.
