+## 서버 배포 (텔레메트리 API)
+
+### 서버 정보
+- 위치: `/opt/telemetry`
+- 서비스: `telemetry.service`
+- 포트: `8000` (systemd에서 `Environment=PORT=8000` 설정)
+
+### 배포 명령어
+
+```bash
+cd /opt/telemetry
+rm -rf temp
+git clone https://github.com/StopDragon/sword-macro-ai.git temp
+cd temp && go build -ldflags="-s -w" -o ../sword-api ./cmd/sword-api && cd ..
+rm -rf temp
+systemctl restart telemetry
+```
+
+### 서비스 관리
+
+```bash
+# 상태 확인
+systemctl status telemetry
+
+# 로그 확인
+journalctl -u telemetry -f
+
+# 재시작
+systemctl restart telemetry
+
+# 중지
+systemctl stop telemetry
+```
+
+### systemd 설정 (/etc/systemd/system/telemetry.service)
+
+```ini
+[Service]
+Type=simple
+User=root
+WorkingDirectory=/opt/telemetry
+ExecStart=/opt/telemetry/sword-api
+Environment=PORT=8000
+Restart=always
+RestartSec=5
+```

+## 클라이언트 빌드
+
+### macOS (ARM64)
+```bash
+CGO_ENABLED=1 GOOS=darwin GOARCH=arm64 go build -ldflags="-s -w" -o builds/sword-macro-darwin-arm64 ./cmd/sword-macro
+```
+
+### macOS (AMD64)
+```bash
+CGO_ENABLED=1 GOOS=darwin GOARCH=amd64 go build -ldflags="-s -w" -o builds/sword-macro-darwin-amd64 ./cmd/sword-macro
+```

+### Windows (AMD64)
+```bash
+CGO_ENABLED=0 GOOS=windows GOARCH=amd64 go build -ldflags="-s -w" -o builds/sword-macro-windows-amd64.exe ./cmd/sword-macro
+```
+
+### 전체 빌드 (로컬)
+```bash
+# macOS ARM64 (네이티브)
+CGO_ENABLED=1 go build -ldflags="-s -w" -o builds/sword-macro-darwin-arm64 ./cmd/sword-macro
+
+# macOS AMD64
+CGO_ENABLED=1 GOARCH=amd64 go build -ldflags="-s -w" -o builds/sword-macro-darwin-amd64 ./cmd/sword-macro
