Getting Started with LibreOffice 6.0

When my Microsoft Office became unusable, and I had difficult trying to reinstall it from the original discs, I decided to use LibreOffice. A really excellent alternative to Microsoft Office, and it's free. But I found that 'Getting Started with Libre Office 6.0' , was, for me, verging on being comprehensive, but incomprehensible. To start with there is no index. Also, LibreOffice is a very powerful program with many features which 90% of users will never need. I think it would be better to divide the book into two sections, the first for users with basic needs, written in simple language without the usual jargon and with good screen shots , and the second covering the advanced features.
