-轻松(做)配置，简单便捷的通用配置文件加载、读取与更新工具，可自定义配置格式。
+**Easy _(to make)_ Configurations!**
 
-## 优势
+A simple, easy-to-use and universal solution for managing configuration files. 
+Enjoy the ease of use with customizable formats for loading, reading, and updating your configuration files.
 
-- 基于类的配置文件初始化、加载、获取与更新机制，方便快捷。
+## Features & Advantages
-- 支持复杂配置的手动序列化、反序列化。
-- 提供多种builder形式，快速构建 `ConfigValue<?>` 对象。
-- 支持通过注解规定配置对应的路径、注释等信息。
 
-## 开发
+- Class-based mechanism for initializing, loading, retrieving, and updating configuration files, ensuring convenience and efficiency.
+- Supports manual serialization and deserialization of complex configurations.
+- Offers multiple builder forms for rapid construction of `ConfigValue<?>` objects.
+- Enables specification of configuration paths, comments, and more via annotations.
