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:
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.
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.
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.

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.
classDiagram
class MyClass {
+publicMethod()
-privateMethod()
}
Customization
Mermaid allows you to customize your diagrams with styles and colors.

style B fill:#bbf,stroke:#f66,stroke-width:2px
