High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I document software architecture using Mermaid diagrams in Markdown?▼

You can document software architecture by writing Mermaid diagram definitions as plain text blocks within Markdown files. This approach replaces lengthy prose with visual representations of system structure and data flows.

What types of Mermaid diagrams can I use to visualize system workflows?▼

Mermaid diagrams support class, sequence, flowchart, ERD, C4, and state diagrams. These types allow you to model system context, API interactions, database schemas, and deployment pipelines.

Do I need to install any external tools to render Mermaid diagrams?▼

No external installations are required to render Mermaid diagrams. You only need a Markdown editor or viewer that supports Mermaid rendering to display the plain text definitions visually.

Can I embed Mermaid flowcharts directly in my pull requests for onboarding?▼

Yes, you can embed Mermaid flowcharts directly in Markdown files and pull requests. This facilitates documentation and onboarding by visually communicating system structure and process flows.

What is the best way to model database schemas without using external diagramming software?▼

Using Mermaid entity relationship diagrams (ERDs) in Markdown is the best way to model database schemas without external software. You define data relationships as plain text and render them in any Mermaid-enabled viewer.

Why use plain text Mermaid definitions instead of image-based architecture diagrams?▼

Plain text Mermaid definitions integrate directly into Markdown files and PRs, unlike image-based diagrams. This ensures architecture documentation remains version-controlled, easily editable, and accessible for onboarding.
