Use when creating Mermaid diagrams, flowcharts, sequence diagrams, state machines, or architecture graphs.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Mermaid.js v11
## Overview
Create text-based diagrams using Mermaid.js v11 declarative syntax. Convert code to SVG/PNG/PDF via CLI or render in browsers/markdown files.
## Quick Start
**Basic Diagram Structure:**
```
{diagram-type}
{diagram-content}
```
**Common Diagram Types:**
- `flowchart` - Process flows, decision trees
- `sequenceDiagram` - Actor interactions, API flows
- `classDiagram` - OOP structures, data models
- `stateDiagram` - State machines, workflows
- `erDiagram` - Database relationships
- `gantt` - Project timelines
- `journey` - User experience flows
See `references/diagram-types.md` for all 24+ types with syntax.
## Creating Diagrams
**Inline Markdown Code Blocks:**
````markdown
```mermaid
flowchart TD
A[Start] --> B{Decision}
B -->|Yes| C[Action]
B -->|No| D[End]
```
````
**Configuration via Frontmatter:**
````markdown
```mermaid
---
theme: dark
---
flowchart LR
A --> B
```
````
**Comments:** Use `%% ` prefix for single-line comments.
## CLI Usage
Convert `.mmd` files to images:
```bash
# Installation
npm install -g @mermaid-js/mermaid-cli
# Basic conversion
mmdc -i diagram.mmd -o diagram.svg
# With theme and background

How to install
mdr add tamnguyendinh/anvien/mermaid-js@sha256:a0731ae5235b343cThe line at the top of this page pins the label git:20260830.ffe03f9, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
