# Display Online Help

You can display IDOL Expert, the IDOL Server Reference, and the IDOL Server Administration Guide by sending an action from your Web browser.

For IDOL to display help, the help data file (`help.dat`) must be available in the same directory as the service instance.

To display help for IDOL

1. Start IDOL server.

2. Send the following action from your Web browser:

       http://IDOLhost:port/action=Help

   where,

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

   For example:

       http://12.3.4.56:9000/action=help

3. On the help landing page, click one of the following options to open the relevant help:

   Admin Guide | The IDOL Server Administration Guide describes how to configure and use IDOL Server.
   Reference | The IDOL Server Reference contains details of all the actions and configuration parameters that you can set in IDOL Server.
   IDOL Expert | IDOL Expert provides conceptual overviews and expert knowledge of IDOL server and its features and functionality.

   If you are new to IDOL, you can use IDOL Expert to find out more about the different functions that IDOL can perform. Use the IDOL Server Administration Guide to get specific information about configuration and administration procedures. Use the IDOL Server Reference to look up specific configuration parameters and actions.
