After you create a topic, you can add to it almost anything you want—text, tables, formatting, cross-references, images, multimedia, etc. It all depends on the needs of your audience. A topic can contain simple text, or it can contain a combination of many elements. A topic does not even need to contain much text at all; for example, you could simply use a topic to hold a video for online output or a few lines of text for the title page in print-based output. You are only limited by what you can do with XML.
If you are not familiar with XML, that's okay. You can use the easy editor interface to edit topics in Flare, working much like you would in a program such as Microsoft Word. Flare creates the XML tags behind the scenes for you.
