KDE Desktop kWalletManager Help File?

I’m running Leap 42.1 with the KDE desktop. In kWalletManager5 the help menu has an entry for “Wallet Manager Manual”. When I select it, nothing happens. I presume there is a file that needs to be downloaded and installed somewhere. (I had to install kWalletManager5 because kde4-WalletManager, installed by default, would not launch).

It’s not a big deal, but can anyone help me fix this?

Thanks,
S. Prows

I solved this issue by searching in YaST for help and discovered that ‘khelpcenter5’ was not installed. Now the help button works.
