How do I generate Mermaid diagrams for software documentation?▼

You generate Mermaid diagrams by providing a natural language request describing your system, such as a user login flow. The skill then outputs ready-to-use Mermaid syntax for software documentation without requiring external tools.

What types of Mermaid diagrams can I create for architecture visualization?▼

You can create flowcharts, sequence diagrams, ER diagrams, class diagrams, state diagrams, and Gantt charts. These cover workflows, data relationships, and architecture visualization for design reviews and onboarding documentation.

Can I document a user login and authorization flow with a Mermaid flowchart?▼

Yes, you can document a user login and authorization flow by requesting a flowchart. The skill provides syntax references and best practices to visualize authentication steps, permission checks, and system workflows accurately.

Do I need external tools to create sequence diagrams and ER diagrams?▼

No external tools are required for basic use. The skill provides built-in syntax references, best practices, and patterns to generate sequence and ER diagrams directly from natural language descriptions of your data relationships.

What is the best way to visualize data relationships using ER diagrams?▼

The best way to visualize data relationships is by requesting an ER diagram pattern. The skill translates your database schema descriptions into standardized Mermaid syntax, reducing manual drawing time for documentation.
