Documentation

README

Excerpt

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:

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

This is the opening of the README. Read the full README on GitHub.
