Installation

From source

To install it from source:

cargo install mdbook-mermaid

This will build mdbook-mermaid from source.

Using cargo-binstall

If you have cargo-binstall already:

cargo binstall mdbook-mermaid

This will download and install the pre-built binary for your system.

Manually

Binary releases are available on the Releases page. Download the relevant package for your system, unpack it, and move the mdbook-mermaid executable into $HOME/.cargo/bin:

Configure your mdBook to use mdbook-mermaid

When adding mdbook-mermaid for the first time, let it add the required files and configuration:

mdbook-mermaid install path/to/your/book

This will add the following configuration to your book.toml:

[preprocessor.mermaid]
command = "mdbook-mermaid"

[output.html]
additional-js = ["mermaid.min.js", "mermaid-init.js"]

It will skip any unnecessary changes and detect if mdbook-mermaid was already configured.

Additionally it copies the files mermaid.min.js and mermaid-init.js into your book's directory. You find these files in the src/bin/assets directory. You can modify mermaid-init.js to configure Mermaid, see the Mermaid documentation for all options.

Finally, build your book:

mdbook path/to/book
