      # ligarb book project

      This is a book project using [ligarb](https://github.com/ko1/ligarb).

      ## Commands

      - `ligarb build` — Build the book (generates build/index.html)
      - `ligarb help` — Show full specification (Markdown syntax, config options, etc.)

      ## Key rules

      - All chapter files are Markdown (.md), listed in book.yml
      - The first h1 in each file is the chapter title
      - Use ```mermaid, ```math, admonitions (> [!NOTE]), etc. as needed
      - Run `ligarb build` after changes to verify the output
