mdbook-reading-time

A processor for mdBook that calculates the reading time and word count of each chapter.

Usage

cargo install mdbook-reading-time

In book.toml

[preprocessor.reading-time]

This configuration replaces:

• {{ #word_count }} with the number of words in the chapter.
• {{ #reading_time }} with reading time, e.g. 9 minutes.

You can customize the default 200 WPM reading speed:

[preprocessor.reading-time]
words-per-minute = 250
