# Getting Started with Mermaid Mermaid lets you create diagrams using text and code, making documentation easier and more maintainable. This guide will introduce you to Mermaid's capabilities and how to begin using it. ## Introduction to Mermaid Mermaid simplifies the process of generating diagrams like flowcharts, sequence diagrams, class diagrams, and more, all from text descriptions. ## How to Use Mermaid To use Mermaid, you typically need a platform that supports it (like GitHub or GitLab) or use it within Markdown editors that have Mermaid integration. ### Basic Syntax Mermaid diagrams are defined using a special syntax code block in Markdown files: ```mermaid graph TD; A-->B; A-->C; B-->D; C-->D; ``` Remove the backslash `\` before the backticks to use this in your Markdown. This example creates a simple flowchart. ## Diagram Types Mermaid supports various diagram types. Here are some of the most common ones: ### 1. Flowcharts Create flowcharts to visualize processes and workflows. ```mermaid graph LR; A[Start] --> B{Decision}; B -->|Yes| C[Do Something with Melodi]; B -->|No| D[Do Something Else]; C --> E[End]; D --> E; ``` ### 2. Sequence Diagrams Sequence diagrams are perfect for showing interactions between actors in a system. ```mermaid sequenceDiagram; participant A as User; participant B as System; A->>B: Request; B->>A: Response; ``` ### 3. Gantt Charts Gantt charts help in visualizing project schedules. ```mermaid gantt title A Gantt Chart dateFormat YYYY-MM-DD section Section A task :a1, 2024-01-01, 30d Another task :after a1 , 20d ``` ### 4. Class Diagrams Class diagrams are useful for representing the structure of a system. ```mermaid classDiagram class MyClass { +publicMethod() -privateMethod() } ``` ## Customization Mermaid allows you to customize your diagrams with styles and colors. ```mermaid graph TD; A-->B; style A fill:#f9f,stroke:#333,stroke-width:4px style B fill:#bbf,stroke:#f66,stroke-width:2px ``` ```mermaid gitGraph commit commit branch develop commit commit commit checkout main commit commit ``` ```mermaid quadrantChart title Reach and engagement of campaigns x-axis Low Reach --> High Reach y-axis Low Engagement --> High Engagement quadrant-1 We should expand quadrant-2 Need to promote quadrant-3 Re-evaluate quadrant-4 May be improved Campaign A: [0.3, 0.6] Campaign B: [0.45, 0.23] Campaign C: [0.57, 0.69] Campaign D: [0.78, 0.34] Campaign E: [0.40, 0.34] Campaign F: [0.35, 0.78] ``` ```mermaid mindmap root((mindmap)) Origins Long history ::icon(fa fa-book) Popularisation British popular psychology author Tony Buzan Research On effectiveness
