TEI By Example offers a series of freely available online tutorials walking individuals through the different stages in marking up a document in TEI (Text Encoding Initiative). Besides a general introduction to text encoding, step-by-step tutorial modules provide example-based introductions to eight different aspects of electronic text markup for the humanities. Each tutorial module is accompanied with a dedicated examples section, illustrating actual TEI encoding practise with real-life examples. The theory of the tutorial modules can be tested in interactive tests and exercises.
