## Project history and usage

mermaid-cli is the command-line front end for Mermaid, the text-to-diagram JavaScript library. The repository describes it as a CLI that takes a Mermaid definition file and produces SVG, PNG, or PDF output; the Mermaid documentation page for the CLI redirects readers to the separate `mermaid-js/mermaid-cli` project.

### Project history

The practical interface is the `mmdc` command, used in documentation builds, CI pipelines, and local authoring workflows where diagrams must be rendered from `.mmd` source files without opening the Mermaid live editor. The package supports global npm installation, Docker-oriented usage, theming, transparent backgrounds, custom CSS injection, and file conversion workflows such as `mmdc -i input.mmd -o output.svg`.

### How it is used

For Homebrew, the package-manager niche is making Mermaid rendering available as a normal system CLI, alongside its npm package identity. It sits between documentation generators and browser automation: users write Mermaid syntax in source-controlled text files, then render stable image or document artifacts for READMEs, static sites, and release documentation.
