# 2.2.3 Configuration

The admin is pre-configured for a **local host** domain of **i2b2demo**. The steps in this section will walk you through how to configure the Admin to a different domain or host.

### Steps to update domain and host

WARNING

Make sure you are editing the files in your **web server directory** and *not* the ones that reside in *YOUR_I2B2_SRC_DIR*.

1. Go to the **admin folder** in your **web server directory**.

***Examples:***

***Linux:***  /var/www/html

***Windows:***  C:\inetpub\wwwroot

2. Open the **i2b2_config_data.js** file.

3. Edit or add additional domains for your environment.

4. It is very important you add the line that says "adminOnly: true" to the file. (See the code block below.) This causes the web client to start in admin mode.

Important

- If you are installing the i2b2 demo environment do not edit the domain "i2b2demo" except to update the *urlCellPM* with your host and port for the location of the PM Cell.
- If you are setting up your own i2b2 environment with test or production data then you can copy the domain section and edit it to reflect your environment.

  **i2b2_config_data.js**

4. Save the changes and close the file.
