The knowledge base consist of categories, sections, and articles. Articles are grouped in sections, and sections are grouped in categories.
To get around the knowledge base, you can use search or browse categories and sections. If available, use breadcrumbs to go home or to a parent section or category. Depending on how your Help Center is configured, you may also have links to browse recently viewed articles, related articles, or promoted articles. You can subscribe to sections or articles so that you're notified when somebody creates an article or comments on an article.
