+
+2. Use `tar -xzvf` to decompress the tar package.
+
+   ```bash
+   $ tar -xzvf nebula-graph-dashboard-<version>.tar.gz
+   ```
+
+3. Use `vim config/config.yaml` to modify the configuration.
+
+   ```bash

+   database:
+     dialect: mysql # The type of database used, which currently only supports MySql
+     host: 192.168.8.157 # The IP address of the connected MySql database

+     username: root # The username to log in MySql
+     password: nebula # The password to log in MySql
+     name: dashboard # The name of the corresponding database
+     autoMigrate: true # Auto database tables creation, the default value of which is true

+   exporter:
+     nodePort: 9100 # The port of the node-exporter service
+     nebulaPort: 9200 # The port of the nebula-stats-exporter service
+   # Information of services

+     prometheus:
+       target: "127.0.0.1:9090" # The IP address and port of the prometheus service
+   ```
+
+4. Copy the license file to the `nebula-dashboard` directory.
+
+   ```bash
+   $ cp -r <license> <dashboard_path>
+   ```
+
+   For example:
+   ```bash
+   $ cp -r nebula.license /usr/local/nebula-dashboard
+   ```
+
+  !!! enterpriseonly
+
+        The license is only available in the Enterprise Edition. To obtain the license, send email to inquiry@vesoft.com.
+
+5. Start Dashboard.
+
+   You can use the following command to start the Dashboard with one click.
+   ```bash
+   $ bash ./scripts/start.sh
+   ```
+   Or execute the following commands to start prometheus, webserver, exporter and gateway services to start Dashboard.
+
+   ```bash
+   $ cd scripts
+   $ sudo ./dashboard.server start prometheus # Start prometheus service
+   $ sudo ./dashboard.server start webserver # Start webserver service
+   $ sudo ./dashboard.server start exporter # Start exporter service
+   $ sudo ./dashboard.server start gateway # Start gateway service
+   ```
+
+## Manage Dashboard Service
+
+You can use the `dashboard.service` script to start, stop, and check the Dashboard services.
+
+### Syntax
+
+```bash
+$ sudo <dashboard_path>/dashboard/scripts/dashboard.service
+[-v] [-h]
+<start|stop|status>  <prometheus|webserver|exporter|gateway|all>
+```
+
+| Parameter                  | Description       |
+| :------------------------- | :------------------- |
+| `dashboard_path` | Dashboard installation path.  |
+| `-v`                       | Display detailed debugging information.   |
+| `-h`                       | Display help information.        |
+| `start`                    | Start the target services.       |
+| `stop`                     | Stop the target services.           |
+| `status`                   | Check the status of the target services.       |

+
+### Examples
+
+Dashboard is installed in the current directory, and you can use the following commands to manage services.
+```bash
+$ sudo /dashboard/scripts/dashboard.service start all #start all Dashboard service 
+$ sudo /dashboard/scripts/dashboard.service stop all #stop all Dashboard service 
+$ sudo /dashboard/scripts/dashboard.service status all #check all Dashboard service 
+```
+
+## Next to do
+
+After Dashboard is successfully started, you can enter `http://<ip_address>:7005` in the address bar of a browser.
+
+If the following login interface is shown in the browser, then you have successfully deployed and started Dashboard. You can log into the GOD user of Dashboard with the default username `nebula` and password `nebula`. You can modify the password in [System Settings](../nebula-dashboard-ent/6.system-settings.md). And you also can use the GOD account to create a new account with the permission ADMIN on the [Account Management](../nebula-dashboard-ent/5.account-management.md) to log into the Dashboard.
