 ## 注意事项
 
+**中国大陆**
+
 - 年份是按照国务院文件标题年份而不是日期年份，12 月份的日期可能会被下一年的文件影响，因此应检查两个文件。
 
 - `与周末连休` 的周末不是法定节假日，数据里不会包含，见[《全国年节及纪念日放假办法》](https://www.gov.cn/zhengce/content/202411/content_6986380.htm) [#213](https://github.com/NateScarlet/holiday-cn/issues/213#issuecomment-1869546011) [#221](https://github.com/NateScarlet/holiday-cn/issues/221)
 
+**香港**
+
+- 香港不设调休补班制度，数据中不会出现 `isOffDay: false` 的条目。
+- 假期名称为繁体中文。
+- 数据覆盖范围取决于港府发布进度，通常提前公布至次年。

+## 数据生成
+
+安装依赖：
+
+```sh
+pip install -r dev-requirements.txt
+```
+
+更新当年及次年数据（所有地区）：
+
+```sh
+python scripts/update.py
+```
+
+只更新指定地区：
+
+```sh
+python scripts/update.py --region cn   # 仅中国大陆
+python scripts/update.py --region hk   # 仅香港
+```
+
+更新所有历史年份（仅中国大陆，香港数据源仅覆盖 2024 年起）：
+
+```sh
+python scripts/update.py --all --region cn
+```
+
+CI 每日自动执行 `python scripts/update.py --release`，数据有变化时自动提交并发布新版本。
+
+## 导入到业务系统（teramesh-backend）
+
+数据通过 Django management command 导入工作日历：
+
+```sh
+# 进入应用容器
+kubectl exec -it pod/teramesh-app-0 -- /bin/sh
+
+# 导入所有地区（中国大陆 + 香港）
+python manage.py populate_working_calendar
+
+# 只导入指定地区
+python manage.py populate_working_calendar --region CN
+python manage.py populate_working_calendar --region HK
+```
+
+命令会导入当年及次年的假期数据。数据按 `country` 级别写入，部署在香港（`country=HK`）的站点自动使用香港假期，内地站点使用内地假期，无需额外配置。
+
+## 扩展支持新地区
+
+如需接入其他地区（如美国、日本等），按以下步骤操作：
+
+**1. 新增数据抓取模块**
+
+在 `scripts/` 下新建 `fetch_{地区代码}.py`，实现 `fetch_{地区代码}_holiday(year: int) -> dict`，返回格式与现有地区一致：
+
+```python
+{
+    "year": 2025,
+    "papers": ["数据来源URL"],
+    "days": [
+        {"name": "假期名称", "date": "2025-01-01", "isOffDay": True}
+    ]
+}
+```
+
+注意：若该地区无调休补班制度，`isOffDay` 始终为 `True`。
+
+**2. 在 `scripts/update.py` 的 `REGIONS` 中注册**
+
+```python
+REGIONS = {
+    "cn": { ... },
+    "hk": { ... },
+    "us": {                              # 新增
+        "fetch": fetch_us_holiday,
+        "start_year": 2024,
+        "subdir": "us",
+        "main_ics_name": "holiday-us.ics",
+        "cal_name": "美国联邦假期",
+        "cal_desc": "美国联邦公共假期数据。",
+    },
+}
+```
+
+**3. 在 `teramesh-backend` 的 `HOLIDAY_SOURCES` 中注册**
+
+```python
+HOLIDAY_SOURCES = {
+    "CN": f"{GITEA_BASE}/{{year}}.json",
+    "HK": f"{GITEA_BASE}/hk/{{year}}.json",
+    "US": f"{GITEA_BASE}/us/{{year}}.json",  # 新增
+}
+```
+
+之后运行 `python manage.py populate_working_calendar --region US` 即可导入，其余地区不受影响。
