## What it is
A command-line interface for rendering Mermaid diagram definition files into SVG, PNG, or PDF outputs. This repository is no longer actively developed; development has moved to mermaid-js/mermaid-cli and the @mermaid-js/mermaid-cli npm package.

## Use cases
- convert mermaid diagrams to svg from the command line
- render .mmd files to png images
- generate pdf diagrams from mermaid definitions
- batch render mermaid charts with custom themes and sizes
- automate diagram generation in build pipelines

## When to choose
- you need a scriptable way to render mermaid diagrams to svg, png, or pdf
- you want to generate diagrams as part of CI or documentation builds

## When to avoid
- starting a new project - use @mermaid-js/mermaid-cli instead, as this package is unmaintained and out-of-date
- you need the latest mermaid features or bug fixes

## Facets
- artifact type: cli-tool
- maturity: abandoned
- function: cli, documentation, image-processing
- domain: developer-tools, documentation
- platform: cli, cross-platform
- tags: mermaid, diagrams, svg, png, pdf, deprecated, moved-to-mermaid-cli, command-line, nodejs
