-# 中关村医疗器械园 智慧能源管理平台 (zpark-ems)
+# Z-Park Medical Device Hub EMS (zpark-ems)
 
-## 项目说明
-中关村医疗器械园EMS客户定制项目，基于 ems-core 标准产品。
+> Z-Park Medical Device Hub Smart Energy Management System
 
-## 园区特点
-- 光伏为主：4,561块太阳能板，分布在22+栋建筑
-- 阳光电源组串式逆变器：AP101-AP208，10台
-- 直流汇流箱：49台
-- 数据采集：通过阳光电源 iSolarCloud API
+**Current Version: 1.2.0** | Core: 1.1.0 | See `VERSIONS.json`
 
-## 目录结构
-- `core/` — EMS核心代码（通过git subtree引入，勿直接修改）
-- `customers/zpark/` — Z-Park专属配置
-  - `config.yaml` — 品牌配置和功能开关
-  - `devices.json` — 阳光电源逆变器和汇流箱设备清单
-  - `pricing.json` — 北京工商业分时电价
-- `scripts/` — Z-Park数据初始化脚本
-- `.env.example` — 环境变量模板（含阳光电源API配置）
+Customer project for Z-Park Medical Device Hub (中关村医疗器械园), built on [ems-core](http://100.69.143.96:3300/tianpu/ems-core).
 
-## 快速开始
-1. 复制环境配置：`cp .env.example core/backend/.env`
-2. 安装后端依赖：`cd core/backend && pip install -r requirements.txt`
-3. 初始化数据库：`cd core/backend && python -m alembic upgrade head`
-4. 导入种子数据：`python scripts/seed_zpark.py`
-5. 启动后端：`cd core/backend && python -m uvicorn app.main:app --port 8000 --reload`
-6. 启动前端：`cd core/frontend && npm install && npm run dev`
-7. 访问：http://localhost:3000（admin / admin123）

-## 阳光电源API配置
-在 `.env` 中填入阳光电源 iSolarCloud API 凭证后，设置 `USE_SIMULATOR=false` 即可接入真实数据。

+
+## Quick Start (Docker)
+
+```bash
+# Configure environment
+cp .env.example .env
+# Edit .env — fill in Sungrow iSolarCloud API credentials
+
+# Start all services
+docker compose -f core/docker-compose.yml -f docker-compose.override.yml up -d
+
+# Seed data
+docker compose -f core/docker-compose.yml -f docker-compose.override.yml exec backend python scripts/seed_zpark.py
+```
+
+### Access
+
+| Service | URL |
+|---------|-----|
+| Frontend | http://localhost:3000 |
+| Backend API | http://localhost:8000 |
+| API Docs | http://localhost:8000/docs |
+
+### Default Login
+
+| Role | Username | Password |
+|------|----------|----------|
+| Admin | admin | admin123 |

+
+## Local Development
+
+### Backend
+
+```bash
+cd core/backend
+python -m venv venv
+source venv/bin/activate  # Windows: venv\Scripts\activate
+pip install -r requirements.txt
+python -m alembic upgrade head
+uvicorn app.main:app --port 8000 --reload
+```
+
+### Frontend
+
+```bash
+cd frontend
+npm install
+npm run dev
+# Opens at http://localhost:3000, proxies /api to localhost:8000
+```
+
+---
+
+## Sungrow API Configuration
+
+Fill in Sungrow iSolarCloud API credentials in `.env`, then set `USE_SIMULATOR=false` to connect to real data.
+

+
+## Updating Core
+
+When ems-core releases a new version:
+
+```bash
+git subtree pull --prefix=core ems-core main --squash
+```
+
+Make sure the `ems-core` remote is configured:
+
+```bash
+git remote add ems-core http://100.69.143.96:3300/tianpu/ems-core.git
+```
+
+After pulling, update `core_version` in `VERSIONS.json`.
