+# Autonomy Studio LMS
 
-lms 프론트엔드
+Autonomy Studio LMS의 학생용 데스크톱 애플리케이션입니다. Electron 기반으로 동작하며, 학습 워크스페이스에서 ROS 2/NAV2 모듈 설치와 실행, 코드 편집, Git 연동, 터미널, 맵 및 시각화를 제공합니다.
+
+로컬 PC 시뮬레이션과 원격 플랫폼 워크스페이스를 모두 지원합니다.
+
+## 주요 기능
+
+- 강좌, 학습 단계, 모듈 기반 워크스페이스 관리
+- 로컬 및 원격 플랫폼의 모듈 설치, 빌드, 실행, 종료
+- 코드 편집기, Git 소스 제어, 내장 터미널
+- ROS 토픽 연결 상태와 모듈 간 발행/구독 관계 확인
+- 2D/3D SLAM 맵 저장 및 주행 시각화
+- Docker 기반 ROS 런타임과 SLAM ROS 브리지 관리
+- 원격 플랫폼 에이전트와 연동한 워크스페이스 및 교보재 제어
+
+## 프로젝트 구조
+
+```text
+src/
+  main/                 Electron main process, Docker/워크스페이스/원격 제어
+  preload/              renderer에 노출하는 IPC API
+  renderer/src/         React 사용자 인터페이스
+resources/
+  slam-ros-bridge/      SLAM 및 시각화용 ROS 브리지
+  bin/                  패키징에 포함되는 실행 파일
+  licenses/             배포 라이선스
+```
+
+## 요구 사항
+
+- Node.js와 npm
+- Docker Engine
+- Git
+- Linux AppImage 패키징 시 필요한 시스템 의존성
+
+GPU 가속을 사용할 경우에는 NVIDIA 드라이버 외에 Docker용 NVIDIA Container Toolkit이 필요합니다. GPU 가속은 Docker 컨테이너에 `--gpus all` 옵션을 전달하므로, Docker 런타임이 GPU를 인식하지 못하면 모듈 실행이 실패합니다.
+
+## 개발 환경 실행
+
+```bash
+cp .env.example .env
+npm ci
+npm run dev
+```
+
+renderer 개발 서버는 기본적으로 `5176` 포트를 사용합니다.
+
+## 환경 변수
+
+`.env.example`을 복사해 로컬 환경에 맞게 설정합니다.
+
+| 변수 | 설명 |
+| --- | --- |
+| `VITE_API_BASE_URL` | LMS 백엔드 API 주소 |
+| `VITE_LAUNCHER_API_BASE_URL` | 런처/플랫폼 API 주소 |
+| `LOCAL_AUTOWARE_BRIDGE_IMAGE` | 로컬 Autoware ROS 브리지 이미지 |
+| `LOCAL_NAV2_BRIDGE_IMAGE` | 로컬 NAV2 ROS 브리지 이미지 |
+| `LOCAL_NAV2_RUNTIME_IMAGE` | 로컬 NAV2 런타임 이미지 |
+| `LOCAL_SLAM_BRIDGE_IMAGE` | 로컬 SLAM ROS 브리지 이미지 |
+| `LOCAL_SLAM_RUNTIME_IMAGE` | 로컬 SLAM 런타임 이미지 |
+| `JETSON_AGENT_URL` | 원격 Jetson 에이전트 주소 |
+| `JETSON_AGENT_TOKEN` | 원격 Jetson 에이전트 인증 토큰 |
+| `JETSON_AUTOWARE_BRIDGE_IMAGE` | 원격 Autoware ROS 브리지 이미지 |
+| `JETSON_NAV2_BRIDGE_IMAGE` | 원격 NAV2 ROS 브리지 이미지 |
+| `JETSON_NAV2_RUNTIME_IMAGE` | 원격 NAV2 런타임 이미지 |
+
+`VITE_` 접두사 변수는 renderer 번들에 포함됩니다. 운영 AppImage를 만들 때는 운영 API 주소로 빌드해야 하며, 토큰이나 비밀번호 같은 민감한 값은 `VITE_` 변수에 넣으면 안 됩니다.
+
+예시:
+
+```bash
+VITE_API_BASE_URL=https://workspace.autonomystudio.net/lms-api/api \
+VITE_LAUNCHER_API_BASE_URL=https://portal-api.autonomystudio.net/api \
+npm run build:linux
+```
+
+## 빌드
+
+```bash
+# Electron main, preload, renderer 빌드
+npm run build
+
+# Linux AppImage 생성
+npm run build:linux
+```
+
+패키징 결과물은 `dist/`에 생성됩니다. AppImage에는 아이콘, SLAM ROS 브리지, 실행 도구, 라이선스 리소스가 함께 포함됩니다.
+
+운영 배포용 AppImage는 관리자 웹의 빌드 변수와 동일한 API 주소, 동일한 소스 커밋을 기준으로 빌드해야 합니다. Kubernetes의 LMS 웹 배포 환경 변수는 Electron AppImage에 런타임으로 주입되지 않습니다.
+
+## 워크스페이스와 맵
+
+모듈, 빌드 결과물, 저장 맵은 선택한 사용자 워크스페이스 루트 아래에 관리됩니다. SLAM 맵은 기본적으로 다음 경로에 저장됩니다.
+
+```text
+<workspace>/maps
+```
+
+앱은 해당 워크스페이스를 Docker 컨테이너의 `/workspace`로 마운트하고, SLAM 브리지에는 `SAVED_MAPS_PATH=/workspace/maps`를 전달합니다.
+
+## GPU 가속
+
+GPU 가속을 켠 상태에서 다음과 비슷한 오류가 발생하면 Docker GPU 런타임이 설정되지 않은 상태입니다.
+
+```text
+failed to discover GPU vendor from CDI
+```
+
+NVIDIA Container Toolkit을 설치하고 Docker를 재시작한 뒤 아래 명령이 정상 동작하는지 확인합니다.
+
+```bash
+docker run --rm --gpus all nvidia/cuda:12.4.1-base-ubuntu22.04 nvidia-smi
+```
+
+GPU 설정이 준비되지 않은 PC에서는 앱 설정에서 GPU 가속을 끈 상태로 사용합니다.
+
+## 로그와 문제 확인
+
+- 앱 renderer 로그는 Electron의 사용자 로그 경로에 `renderer.log`로 기록됩니다.
+- 모듈 실행 실패는 워크스페이스 화면의 모듈 로그와 Docker 컨테이너 로그를 함께 확인합니다.
+- 원격 플랫폼 문제는 에이전트 상태, Tailscale/Headscale 연결, ROS Domain ID, 원격 Docker 이미지를 순서대로 점검합니다.
+
+## 보안 유의 사항
+
+- `.env`는 저장소에 커밋하지 않습니다.
+- 에이전트 토큰, API 키, 인증 정보는 빌드 변수 또는 별도 비밀 저장소로 관리합니다.
+- 운영 배포 전에는 API 주소와 원격 런타임 이미지 태그가 대상 환경과 일치하는지 확인합니다.

+# Korean and English UI
+
+Use the language selector at the top of the studio settings screen (local or
+remote workspace). Select a language and press Save to apply it. Unsaved choices
+do not change the UI or stored preference. Korean is the default. The choice is
+stored under `autonomy-studio.lms.language` in local storage and applies on the
+next launch. Switching language updates React subscribers without remounting the
+workspace, terminal, editor, or visualization iframe.
+
+## Scope
+
+- App navigation, curriculum UI, studio controls, settings, dialogs and help.
+- Known application status/error messages and NAV2/SLAM viewer controls.
+- Course titles, learning content, materials, module names, source code, terminal
+  output and server-authored notifications remain in their original language.
+- Unrecognized backend/SSH/Docker errors are preserved verbatim for diagnosis.
+- Embedded text in guide images and external pages is not translated.
+- This does not change ROS, Docker, SSH, the OS locale, or module parameters.
+
+## Adding Text
+
+Use `t('Korean source text')` from `src/renderer/src/i18n` at the display boundary
+and add the English value to `en.json`. Call `useLocaleRender()` in components
+which render translations so an open screen reacts to language changes.
+
+Keep identifiers and state values unchanged. Do not translate stored form values,
+parameter strings, module identifiers, or values used in conditions. Use whole
+sentences with named interpolation placeholders instead of joining translated
+fragments. Korean falls back to the source key; unknown messages retain the source.
+
+The standalone SLAM viewer uses `public/slam-viewer/locale.js` and explicitly
+marked text/attributes. It follows the same saved preference through storage
+events, without reconnecting the bridge or resetting the scene.
+
+## Verification
+
+```sh
+npm run test:i18n
+npx tsc --noEmit -p tsconfig.web.json
+npm run build
+```
+
+The tests cover language persistence, storage failure, cross-window updates,
+interpolation, source fallback and literal translation-key coverage. Browser
+checks should additionally cover both languages, narrow studio panels, preserving
+unsaved edits, and language changes with the viewer open. `npm run build` does not
+package an AppImage.

-# Nav2 Development Image
-
-`nav2-dev:humble` is the source-build runtime for Nav2 learning modules. It
-contains ROS 2 Humble, Gazebo, colcon, and rosdep, but intentionally does not
-contain Nav2, TurtleBot3, or SLAM Toolbox source code.
-
-Build it from this directory:
-
-```bash
-./build.sh
-```
-
-Mount a composed module workspace and build its sources:
-
-```bash
-docker run --rm -it --network host \
-  -e DISPLAY="$DISPLAY" \
-  -e TURTLEBOT3_MODEL=burger \
-  -v /tmp/.X11-unix:/tmp/.X11-unix \
-  -v "$HOME/autonomy-studio/workspaces/nav2-slam_ws:/workspace/nav2-slam_ws" \
-  nav2-dev:humble bash
-
-cd "$NAV2_WORKSPACE"
-rosdep install --from-paths src --ignore-src -r -y
-colcon build
-```
-
-The composed workspace must contain all direct source dependencies. For Nav2,
-include its shared packages such as `nav2_common`, `nav2_util`, and `nav2_msgs`
-alongside the module packages being built.
-
-On later container starts, the entrypoint automatically sources
-`/workspace/nav2-slam_ws/install/setup.bash`, so source-built packages override
-the base ROS installation.
