# Add a KeyView Service

To use the File Content Extraction processors you must configure a controller service that stores configuration details for File Content Extraction. The controller service can be used by multiple processors, so you only need to configure File Content Extraction once.

To create the KeyView controller service

1. Right-click a blank area of the canvas and click Controller Services.

   The Controller Services page opens.

2. Click Create a new controller service .

   The Add Controller Service dialog box opens.

3. In the list, click KeyViewFilterServiceImpl, and click ADD.

   The new service is added.

4. Enable the service. At the end of the row for the controller service, click followed by Enable.

   The Enable Controller Service dialog box opens.

5. Click Enable and then click Close.
