Is there a manual for Avira Password Manager?

I appreciate there are lots of online resources for Avira Password Manager. Is there also a manual I could read, to get a very full understanding of how to use the software? This would typically be like a small book, but instead of being on paper, it would typically be a .pdf file, organised into chapters, with a clickable index at the end of it, so one can easily jump around the file, as one clicks on different topics that interest oneself.
