LibreOffice Draw Help text problem

I have installed only the Draw component ( of LibreOffice. I also installed the help facility. If I select Help from Draw, it loads the help facility with a list of subjects in the left pane. However, on selecting any subject, no further information is shown. I was expecting something to appear in the right hand pane to explain it. Have I misunderstood how the help in LibreOffice works or is there something missing?

Can you provide informations about used operating system and LibreOffice version?
