| Best use | For developers and small teams that want architecture and data-flow diagrams close to the repository and reviewable as text. Use it when relationships matter more than pixel-perfect placement; not for free-form marketing design or exact manual positioning. | For documentation authors and small teams checking references locally or in CI. Start with a specific file and interpret findings; it does not establish complete site or login functionality. | Best for a developer or small team maintaining a product or library guide and comfortable with files and Git. It organizes scattered instructions into pages with clear locale and version choices. It does not write or translate your content, and may be excessive for a single page or a team needing direct collaborative editing. |
