+=head1 ANNOTATION SUPPORT
+
+L<KorAP::XML::Krill> has built-in importer for some annotation foundries and layers
+developed in the KorAP project that are part of the KorAP preprocessing pipeline.
+The base foundry with paragraphs, sentences, and the text element are mandatory for
+L<Krill|https://github.com/KorAP/Krill>.
