+# Database Initialization
+
+First create a user in the mariadb:
+
+```bash
+sudo mariab -u root -p
+```
+```sql
+CREATE USER '<user>'@'localhost' IDENTIFIED BY '<password>';
+GRANT ALL PRIVILEGES ON *.* TO '<user>'@'localhost' WITH GRANT OPTION;
+FLUSH PRIVILEGES;
+```
+
+Then modify the `.env` file:
+
+```bash
+SERVICE_ARCHITECTURE_USER=user
+SERVICE_ARCHITECTURE_PASSWORD=password
+```
+
+**And finally run the `init.sh` to create the database.**
+
+> If you want to update the database, it is recommended to run `remove.sh` before hand.
