Comprehensive guide for creating software diagrams using Mermaid syntax. Use when users need to create, visualize, or document software through diagrams including class diagrams (domain modeling, object-oriented design), sequence diagrams (application flows, API interactions, code execution), flowcharts (processes, algorithms, user journeys), entity relationship diagrams (database schemas), C4 architecture diagrams (system context, containers, components), state diagrams, git graphs, pie…
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 Diagramming Create professional software diagrams using Mermaid's text-based syntax. Mermaid renders diagrams from simple text definitions, making diagrams version-controllable, easy to update, and maintainable alongside code. ## Core Syntax Structure All Mermaid diagrams follow this pattern: ```mermaid diagramType definition content ``` **Key principles:** - First line declares diagram type (e.g., `classDiagram`, `sequenceDiagram`, `flowchart`) - Use `%%` for comments - Line breaks and indentation improve readability but aren't required - Unknown words break diagrams; parameters fail silently ## Diagram Type Selection Guide **Choose the right diagram type:** 1. **Class Diagrams** - Domain modeling, OOP design, entity relationships - Domain-driven design documentation - Object-oriented class structures - Entity relationships and dependencies 2. **Sequence Diagrams** - Temporal interactions, message flows - API request/response flows - User authentication flows - System component interactions - Method call sequences 3. **Flowcharts** - Processes, algorithms, decision trees - User journeys and workflows - Business processes …

How to install
mdr add pantheon-org/tekhne/mermaid-diagrams@sha256:eabc93407ab80712The line at the top of this page pins the label git:20260710.bdf81d7, 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.
