-# ODF 光纤配线单元管理系统
+# Simple Hello API
 
-本项目是一个 ODF（Optical Distribution Frame，光纤配线架）配线单元管理系统的 Python 示例工程。使用 FastAPI 构建，采用内存假数据存储，无需外部基础设施。
+一个最简单的 FastAPI 单体示例工程。
-
-## 功能特性
-
-- 管理 ODF 机架（Rack）：添加、查询、删除
-- 管理配线单元（Unit）：每个机架包含多个配线单元
-- 管理光纤端口（Port）：每个单元包含多个光纤端口
-- 管理跳接连接（Connection）：记录端口之间的跳纤关系
-- 查询空闲端口、指定端口的连接路径
