+\subsection{Chapter numbering}{
+
+Like in the old Google Docs slide workflow, chapter headings (\verb{#}) are
+numbered automatically: the first chapter becomes "1. Introduction", the
+second "2. Methods", and so on. References, appendix and thank-you
+chapters (References/Literatur/Referenzen/Publikationen/
+Herausgeberschaften/Appendix/Anhang, and headings containing
+"Thank you"/"Vielen Dank") keep their bare titles and are not counted.
+Manually typed leading numbers (\verb{# 2. Methods}) are stripped before
+renumbering, so decks migrated from the old pipeline and repeated
+numbering runs stay stable. The numbers are added when the presentation
+is opened: the menu plugin and the transcript view show them, too, and
+the overview slide's table of contents uses them as its ordered list's
+enumeration. Decks rendered with \code{slide_level = 1} (one \verb{#} heading per
+slide) are left unnumbered -- there, headings denote slides, not
+chapters.

 \subsection{Overview slides}{
 
 Like in the original Google Docs slide workflow, a slide titled
 "Overview" or "Überblick" is automatically turned into a table of
 contents: its body content is replaced at presentation time with a
-clickable list of all \verb{#} chapter headings. Adding
+clickable, ordered list of all \verb{#} chapter headings, whose enumeration
+repeats the chapter numbers. Adding
 \code{{data-overview-subheadings=true}} to the heading also includes the
 \verb{##} sub-headings below their chapters, laid out in two columns.
-References and appendix chapters (References/Literatur/
-Literaturverzeichnis/Appendix/Anhang) are left out, together with
-their sub-slides.
