FAQPage Schema
How do I generate C4 architecture diagrams using Mermaid?▼

To generate C4 architecture diagrams using Mermaid, you prompt the AI to analyze your codebase and output system context, container, component, and deployment diagrams. This reduces manual drafting by automatically identifying system boundaries and dependencies.

What is the C4 model used for in software documentation?▼

The C4 model is used in software documentation to create consistent, reusable architecture diagrams at varying levels of detail. It communicates system context, containers, components, and deployment views to stakeholders, reducing onboarding time.

Can I automatically analyze my codebase to identify components and relationships for system design?▼

Yes, you can analyze a codebase to identify components and relationships for system design. The process inspects your code to map system boundaries and dependencies, then outputs Mermaid-based diagrams to visualize the architecture.

Does this approach work for varying project sizes?▼

Yes, this C4 diagram generation approach applies to varying project sizes. It scales to produce the required system context, container, component, and deployment diagrams based on your specific stakeholder needs.

What is the best way to document system context and containers for stakeholders?▼

The best way to document system context and containers for stakeholders is generating C4 diagrams with Mermaid. This combines narrative text with visual diagrams, clearly communicating architecture and reducing manual drafting efforts.
