-## How to use H2
+## How to use PostgreSQL
+
+### Prerequisites
+
+- PostgreSQL 12 ~ 16. For other versions, the community has not tested fully
and may not be compatible.
+- Gravitino distribution package with version `0.6.0` or above.
+- PostgreSQL connector Jar (Should be compatible with the version of
PostgreSQL instance).
+
+### Step 1: Get the initialization script
+
+You need to `download` and `unzip` the distribution package firstly, please see
+[How to install Gravitino](how-to-install.md).
+
+Then you can get the initialization script in the directory:
+
+```text
+${GRAVITINO_HOME}/scripts/postgresql/
+```
+
+The script name is like `schema-{version}-postgresql.sql`, and the `version`
depends on your Gravitino version.
+For example, if your Gravitino version is the latest release version, then you
can choose the **latest version** script.
+If you used a legacy script, you can use `upgrade-{old version}-to-{new
version}-postgresql.sql` to upgrade the schema.
+
+### Step 2: Initialize the database
+
+Please create a database and scheam in PostgreSQL in advance, and execute the
initialization script obtained above in the database.
