3. Code blocks
4. Basic syntax
5. Flowcharts
6. Sequence diagrams
7. State diagrams
8. Class diagrams
9. ER diagrams
10. Gantt charts
11. Kanban boards
12. Pie charts
13. XY charts
14. Requirement diagrams
15. GitGraph
16. Architecture diagrams
17. Packet diagrams
18. Styling
19. Layouts
20. Interactivity
21. Configuration
22. Plugins and integrations
23. Troubleshooting
24. Performance
25. Security
26. Exercises
27. Quick reference
28. Best practices

The central idea remains simple:

flowchart LR
    Idea[Describe the diagram with text]
    Code[Write Mermaid syntax]
    Render[Mermaid renders the diagram]

    Idea --> Code --> Render

Once the basic syntax is understood, increasingly complex diagrams can be built incrementally while keeping the source readable, editable, and version-controlled.
