+### Build Cache
+
+CI 빌드 속도 향상을 위해 S3 기반 원격 빌드 캐시를 사용합니다.
+
+**로컬에서 캐시 업로드:**
+
+1. `.env` 파일에 AWS 자격 증명 설정:
+   ```
+   AWS_ACCESS_KEY_ID=your_access_key_id
+   AWS_SECRET_ACCESS_KEY=your_secret_access_key
+   ```
+
+2. 캐시 업로드 실행:
+   ```bash
+   ./gradlew warmCache
+   ```
+
 ### Deployment
 
 1. Create a `release-${version-code}` branch and modify the version code in `version.properties`.
