Update Help or Use Offline Help for Presto
By default, help buttons within Presto point to online topics in the Presto Library based on a configuration property defined in the Presto Repository. You must update this configuration property if you migrate to a new Presto release but continue to use your existing Presto Repository.
You must also update this property if you want help in Presto to point to an offline copy of the Presto Library. This is useful if your organization has network restrictions that prohibit access to external networks.
To update help configuration to the online Presto Library for a new Presto release: 1. Find the exact URL to use in the Migration section of the Presto Release Notes for the new release.
2. Click 
Admin Console in the Presto Hub main menu. 3. Open the Server section and click Help Library.
4. Enter the base URL found in the first step.
5. Save your changes.
To update configuration for offline access: 1.
2. Unzip the Presto Library and host it in a web server or application server that the Presto Server can access.
3. Click Admin Console in the Presto Hub main menu. 4. Open the Server section and click Help Library.
5. Enter the base URL to the offline Presto Library including a trailing /.
If you unzipped the offline Presto Library in a web server with an address of http://192.168.1.5:80/, for example, the URL to enter as the base URL would be http://192.168.1.5:80/prestodocs-offline/.
6. Save your changes.
