To read this book, you just need to be comfortable with using your computer. You need to understand how the directories can be organized and used. Except for that, just manipulating the mouse, being patient, and being creative will be the most desirable qualities you'll need. Of course, having some knowledge in other software can be helpful, especially on photo retouching, for example with GIMP, vector drawing like Inkscape, or Office suite. This book doesn't explain all this. However, any document you'll import into Scribus will need to be prepared beforehand and will have to be well managed from the beginning to the end.
