 **Claude Science를 사용하시나요?** 네 개의 스킬을 바로 가져올 수 있습니다: **Skills → Import from GitHub**에서 `https://github.com/Imbad0202/academic-research-skills`를 붙여넣고 **Preview** → **Import 4 skills**(이 저장소 v3.14.0+ 필요 — 가져오기 도구는 marketplace manifest에 명시된 스킬 경로를 읽습니다). 가져오기는 특정 시점의 스냅샷입니다: ARS 업데이트 후에는 다시 가져오세요. 가져온 스킬은 ARS 방법론(연구/작성/리뷰 프로토콜)을 담습니다. Claude Code 전용 메커니즘 — slash commands, hooks, 서브에이전트 오케스트레이션 — 은 이전되지 않습니다. 자세한 내용은 [docs/SETUP.md](docs/SETUP.md) Method 5를 참조하세요.

 **Using Claude Science?** The four skills import directly: **Skills → Import from GitHub**, paste `https://github.com/Imbad0202/academic-research-skills`, **Preview**, then **Import 4 skills** (requires v3.14.0+ of this repo — the importer reads the explicit skill paths in the marketplace manifest). Imports are point-in-time snapshots: re-import after ARS updates. Imported skills carry the ARS methodology (research / writing / review protocols); Claude Code-specific machinery — slash commands, hooks, subagent orchestration — does not transfer. See [docs/SETUP.md](docs/SETUP.md) Method 5 for details.
 
+**Using Pi?** Install the in-tree, community-maintained wrapper with `pi install git:github.com/Imbad0202/academic-research-skills`. It keeps the original ARS content authoritative and documents Pi-specific orchestration and hook limitations. See [`pi/README.md`](pi/README.md).
+
 **Using Codex CLI?** Install the sibling distribution instead: [`Imbad0202/academic-research-skills-codex`](https://github.com/Imbad0202/academic-research-skills-codex) — same workflow content, Codex-native packaging as a single `$academic-research-suite` skill with `ars-*` aliases.
 
 **Third-party platforms and integrations** that wrap or host ARS are listed in [THIRD_PARTY.md](THIRD_PARTY.md) — community-submitted and not reviewed or endorsed by the maintainer.
