+# FlyPython repository guide
+
+## Mission
+
+This repository is the broad, community-maintained resource catalog behind
+FlyPython. Keep `flypython.com` focused on editorial learning paths and a small
+featured set; keep this repository focused on the larger reviewed catalog and
+its contribution workflow.
+
+## Content rules
+
+- Prefer official documentation and primary sources.
+- Every catalog entry must include a stable ID, path, source type, level,
+  rationale, review date, status, and any key or safety requirements.
+- Do not call a project production-ready without current maintenance, licensing,
+  security, and adoption evidence.
+- Do not use an LLM or web-search API to generate resource descriptions.
+  Descriptions and classifications require human review.
+- Keep English and Chinese pages generated from the same canonical resource
+  data. Do not hand-copy the full catalog into multiple Markdown files.
+- Treat HTTP 403, 429, and transient 5xx responses as review-needed states, not
+  automatic proof that a resource is broken.
+
+## Change workflow
+
+- Work on a feature branch and preserve unrelated contributor changes.
+- Run the repository validation workflow before committing.
+- Keep external-link checks read-only, rate-limited, retryable, and blocked from
+  private or loopback network targets.
+- Do not add API keys, tokens, analytics IDs, or generated reports to git.
+- After merge, verify the GitHub Pages deployment and the production domain.
+
+## Review priorities
+
+1. Content accuracy and source quality.
+2. Deterministic generation and bilingual parity.
+3. Build, schema, link, accessibility, and SEO checks.
+4. Clear contribution and licensing boundaries.
