 # Introduction
 
-This module is the mysql registry plugin module, this plugin will use mysql as the registry center.
+This module is the jdbc registry plugin module, this plugin will use jdbc as the registry center. Will use the database configuration same as DolphinScheduler in api'yaml default.
 
 # How to use
 
-## Use Mysql as registry center
+1. Initialize the database table
-If you want to set mysql as the registry center, you need to do the below two steps:
 
-1. Initialize the mysql table
+- If you use Mysql you can directly execute the sql script `src/main/resources/mysql_registry_init.sql`.
 
-You can directly execute the sql script `src/main/resources/mysql_registry_init.sql`.
+- If you use Postgresql you can directly execute the sql script `src/main/resources/postgresql_registry_init.sql`.
 
-2. Open the config
+2. Change the config
 
 You need to set the registry properties in master/worker/api's appplication.yml
 
+```yaml
+registry:
+  type: jdbc
+```
+
+After do this two steps, you can start your DolphinScheduler cluster, your cluster will use mysql as registry center to
+store server metadata.
+
+NOTE: You need to add `mysql-connector-java.jar` into DS classpath if you use mysql database, since this plugin will not bundle this driver in distribution.
+You can get the detail about <a href="https://dolphinscheduler.apache.org/en-us/docs/3.1.2/guide/installation/pseudo-cluster">Initialize the Database</a>.
+
+## Optional configuration
+
+```yaml
+registry:
+  type: jdbc
+  # Used to schedule refresh the ephemeral data/ lock.
+  term-refresh-interval: 2s
+  # Used to calculate the expire time,
+  # e.g. if you set 2, and latest two refresh error, then the ephemeral data/lock will be expire.
+  term-expire-times: 3
+```

+## Use different database configuration for jdbc registry center
