# Display Online Help

You can display the Media Server Reference by sending an action from your web browser. The Media Server Reference describes the actions and configuration parameters that you can use with Media Server.

For Media Server to display help, the help data file (`help.dat`) must be available in the installation folder.

To display help for Media Server

1. Start Media Server.

2. Send the following action from your web browser:

       http://host:port/action=Help

   where:

   `host` | is the IP address or name of the machine on which Media Server is installed.
   `port` | is the ACI port by which you send actions to Media Server (set by the `Port` parameter in the `[Server]` section of the configuration file).
