The 3rd section of the documentation shows the possibilities for the user to structure a project, i.e. to subordinate or superordinate articles to each other, thus creating a hierarchical, logical and clear structure. Furthermore, this chapter deals with the networking of articles with other sources of information and knowledge, more precisely: with links in articles to files, file folders, references, web addresses and other articles. The categorization of articles and the assignment of characteristics can also be very useful for structuring projects.
