FAQPage Schema
How do I generate software architecture diagrams from text for version control?▼

You generate software architecture diagrams from text by using Mermaid syntax to create class, sequence, flowchart, ERD, C4, state, git, and Gantt charts. This text-based approach allows diagrams to be stored and versioned directly alongside your code.

Can I document a database schema using an ERD without graphical tools?▼

Yes, you can document a database schema using an ERD without graphical tools by writing text-based Mermaid syntax. This generates version-controllable entity-relationship diagrams dynamically, eliminating the need for complex visual editors.

What is the best way to visualize a complex API flow in documentation?▼

The best way to visualize a complex API flow is by creating a sequence diagram using Mermaid's text-based syntax. This approach makes your documentation dynamic and allows the flow to be easily updated and versioned with your code.

Do I need to understand Mermaid syntax to create flowcharts and Gantt charts?▼

Yes, effective creation of flowcharts, Gantt charts, and other diagram types requires an understanding of Mermaid syntax. The Skill generates these visualizations directly from the text-based definitions you provide.

Does this approach support C4 and state diagrams for software modeling?▼

Yes, this approach supports C4 and state diagrams for software modeling. You can generate these visualizations, alongside class, sequence, ERD, git, and Gantt charts, using simple text syntax for dynamic documentation.
