+# Contributor Quickstart
+
+This quickstart is for small, review-friendly pull requests, especially doc and test fixes.
+
+## 1) Set up a branch
+
+```bash
+git checkout -b docs/contributor-quickstart
+```
+
+## 2) Keep changes scoped
+
+- One topic per PR (docs-only, test-only, or one bug fix).
+- Avoid mixing formatting churn with functional changes.
+- Keep filenames and commit message clear and searchable.
+
+## 3) Minimal validation before opening PR
+
+For docs-only PRs:
+
+- Verify links and paths resolve.
+- Verify Markdown renders correctly.
+- Run a spelling/typo pass on changed sections.
+
+For code/test PRs:
+
+- Run the smallest relevant local test target first.
+- Include exact commands and results in PR description.
+
+## 4) PR description template
+
+Use this shape:
+
+1. **What changed**
+2. **Why this change is needed**
+3. **How it was validated**
+4. **Risk / rollback notes** (if any)
+
+## 5) Good first PR candidates
+
+- Clarify outdated docs and onboarding instructions.
+- Fix dead links or path typos.
+- Improve test/docs comments that reduce reviewer ambiguity.
+
+Small, well-justified PRs generally review faster than broad refactors.
+
+## 6) Common pitfalls to avoid
+
+- Do not combine unrelated fixes in one PR.
+- Do not include generated or local-environment files by accident.
+- Do not force-push repeatedly after review starts unless strictly necessary.
+- Do not leave validation claims without exact command output.
+
+## 7) Final pre-push checklist
+
+1. Re-read changed files once for clarity and typos.
+2. Re-run the smallest relevant validation command.
+3. Confirm `git status` only shows intended files.
+4. Ensure PR description includes validation and rollback note.
