 To produce an inline citation, call \autodoc:command{\csl:cite{<key>}}, which will typeset something like “(Jones 1982)”.
+If you want to cite a particular page number, use \autodoc:command{\csl:cite[page=22]{<key>}}. Other “locator”  options are available (article, chapter, column, line, note, paragraph, section, volume, etc.) – see the CSL documentation for details.
+Some frequent abbreviations are also supported (art, chap, col, fig…)
 
 To produce a bibliography of cited references, use \autodoc:command{\printbibliography}.
 After printing the bibliography, the list of cited entries will be cleared. This allows you to start fresh for subsequent uses (e.g., in a different chapter).
