+
+## Frontmatter requirements
+
+Every doc should include:
+
+- `id`
+- `title`
+- `description`
+- `sidebar_position`
+
+## Writing rules
+
+- Prefer concrete steps over abstract prose.
+- Provide copy-pasteable examples.
+- State defaults and constraints explicitly.
+- Use absolute `/docs/...` URLs and include the version segment when needed.
+- For current docs, use `/docs/next/...` links.
+- For versioned docs, link within that version (for example `/docs/...` in `version-0.1.20`).
+
+## PR expectations
+
+Any user-visible behavior change should include matching docs updates.

+
+## Is docs content bundled for self-hosted installs?
+
+Yes. The docs static build is bundled and served locally at `/docs`.
+
+## How are docs versions managed?
+
+Docs are versioned using Docusaurus versions, intended to map to release tags.
+
+## Where should contributors edit docs?
+
+Edit files under `docs-site/docs` for latest docs.
+
+## What does this cost in practice?
+
+Real-world reference: from early December 2025 to mid-February 2026, with heavy usage and testing (about 10 to 15 applications per day), easily more than 3000 jobs scored, total LLM spend was about **$12 USD** using Gemini 3 Flash through OpenRouter.
+
+Cost varies by:
+
+- selected model/provider
+- prompt volume and size
+- number of jobs scored/tailored per run
+
+For this workload, Gemini 3 Flash has been low-cost while still producing high-quality outputs.
