This technical document provides detailed documentation of the Prague Dependency Treebank, version 2.0 (PDT 2.0). It includes a detailed complex description of the rules that have been used so far for the annotation of Czech sentences on the tectogrammatical layer both in linguistic and technical respect. The annotated data do not always reflect the described state of the rules precisely, therefore the technical document includes also a detailed description of the tectogrammatical trees that are annotated in PDT 2.0.
