 Standalone only for quick experience for DolphinScheduler.
 
-If you are a new hand and want to experience DolphinScheduler functions, we recommend you install follow Standalone deployment. If you want to experience more complete functions and schedule massive tasks, we recommend you install follow [pseudo-cluster deployment](pseudo-cluster.md). If you want to deploy DolphinScheduler in production, we recommend you follow [cluster deployment](cluster.md) or [Kubernetes deployment](kubernetes.md).

 > **_Note:_** Standalone only recommends the usage of fewer than 20 workflows, because it uses in-memory H2 Database in default, ZooKeeper Testing Server, too many tasks may cause instability.
 > When Standalone stops or restarts, in-memory H2 database will clear up. To use Standalone with external databases like mysql or postgresql, please see [`Database Configuration`](#database-configuration).
