+# Chapter markers
+
+In addition to the captions, you may also want to create a separate
+file noting chapter marks for use in the video player. You can send
+chapter markers as timestamps and text (hh:mm:ss note, one per line)
+or as WebVTT files that look something like this:
+
+```text
+WEBVTT
+
+00:00:01.360 --> 00:02:06.006
+Introduction
+
+00:02:06.007 --> 00:05:27.537
+What is BinDat?
+```

+For an example of how chapter markers allow people to quickly navigate videos, see https://emacsconf.org/2021/talks/bindat/ .
