+# invyone homepage
+
+AI 에이전트 기반 노코드 엔터프라이즈 플랫폼 invyone의 랜딩 페이지.
+
+- 운영 도메인: https://www.invyone.com
+- 솔루션(앱) 링크: https://solution.invyone.com/login
+
+## 배포
+
+`main` 브랜치에 push하면 Gitea Actions가 자동으로:
+
+1. Docker 이미지 빌드 (`localhost:5000/invyone/homepage:<sha>`)
+2. 로컬 레지스트리에 push
+3. K8s `invyone-homepage` 네임스페이스로 rolling update
+
+## 로컬 미리보기
+
+```bash
+docker build -t invyone-homepage .
+docker run --rm -p 8080:80 invyone-homepage
+# → http://localhost:8080
+```
+
+## 구조
+
+```
