+The extension searches for markup files in configurable paths to append the markup to the documents. The markup files must conform to a naming convention to be found. The files must start with the position where the document should be extended and end with the markup file extension (e.g `adoc` or `md`). See documentation of <<Extensions points>>.

+All documents:
