 B<mkdocs-prep> prepares a markdown document for B<mkdocs> processing.
 
-The document is treated as a mustache template
+The document is converted using inline hint section to a mustache template
 and resolved using an external set of single-word tokens.
 
+A document section named "Special strings" is parsed for token definitions
+where each line lists a single-word token, a colon, and default string.
+The section is then stripped,
+and all occurences of default strings are replaced with tokens
+wrapped with double curly brackets.
+
 Template tokens are gathered from external config file F<site.mk>,
 where each line lists a token, an equals sign, and replacement string.
