Tools
Sphinx, MkDocs, Astro and other generators optimize for different content models and teams. Choose by authoring workflow, extensibility, localization and maintenance cost instead of feature-list enthusiasm. A generator demo can look excellent and still be wrong for your documentation.

Practice
A documentation tree that works at fifty pages can fail at five hundred. Build navigation around user tasks, content types and durable concepts before the archive becomes a map of the org chart. Small documentation sets can survive almost any navigation scheme.

API
An OpenAPI description can generate accurate reference structure, but developers still need concepts, task flows, authentication guidance, examples and failure recovery that a schema alone cannot explain. OpenAPI is excellent at describing operations, parameters, request and response shapes, status codes and reusable schemas.

Standards
Consistency at scale comes from content models, terminology and reusable patterns, not from asking every contributor to memorize a giant style guide. Encode the rules that matter in schemas and components. A small team can rely on shared habits and direct editing.
