FAQPage Schema
How do I create flowcharts and sequence diagrams from text for version-controlled documentation?

You can create Mermaid diagrams by defining structure in text, which renders into flowcharts and sequence diagrams for version-controlled documentation. The Skill uses frontmatter configuration to apply themes and layouts.

What is the best way to generate class diagrams and ERDs for software architecture planning?

Mermaid diagrams provide a text-based approach to generate class diagrams and ERDs for architecture planning. Comprehensive references and examples guide implementation of domain structures and relationships.

Can I use frontmatter to configure themes and layouts for Mermaid diagrams?

Yes, you can use a structured frontmatter-driven configuration to define themes, layouts, and export options for Mermaid diagrams. This enforces consistent rendering when creating class diagrams, flowcharts, and C4 diagrams.

Does this approach support C4 diagrams and ERDs for documenting software design?

Yes, this approach supports C4 diagrams and ERD diagrams alongside class diagrams and sequence diagrams for software design. It applies text-based rendering to document engineering and architecture tasks efficiently.

When do I need text-based diagrams instead of other software design documentation methods?

You need text-based diagrams when maintaining version-controlled design documentation for software architecture. Mermaid diagrams allow you to update flowcharts, ERDs, and sequence diagrams directly alongside your source code.
