+# Kiri Core Framework Documentation
+
+## Project Introduction
+
+Kiri is a high-performance PHP-based core framework designed to provide developers with a simple and efficient development experience. The framework includes a variety of practical utility classes, exception handling mechanisms, configuration management, and a dependency injection container, making it suitable for building various types of applications.
+
+### Key Features
+- **Dependency Injection Container**: Provides powerful dependency management via `Kiri\Di\Container`.
+- **Configuration Management**: Supports reading configuration from files and environment variables.
+- **Exception Handling**: Offers a unified exception handling interface with support for registering custom exception handlers.
+- **Logging**: Built-in `StdoutLogger` supporting multiple log levels.
+- **Utility Classes**:
+  - `Str`: String operations such as encryption and random string generation.
+  - `Json`: JSON encoding/decoding and response construction.
+  - `Help`: Auxiliary functions including XML conversion, random number generation, and email sending.
+  - `DateFormat`: Date and time formatting tools.
+- **Networking**: Supports local IP retrieval and Socket programming.
+- **NoSQL Support**: Provides client wrappers for Redis and MongoDB with connection pool management.
+
+## Installation
+
+### System Requirements
+- PHP 7.4 or higher
+- Composer (for dependency management)
+
+### Installation Steps
+1. Ensure Composer is installed.
+2. Run the following command to install dependencies:
+   ```bash
+   composer install
+   ```
+
+## Usage Guide
+
+### Initialize the Framework
+```php
+use Kiri\Kiri;
+use Kiri\Application;
+
+// Initialize the container
+Kiri::setContainer(new Container());
+
+// Create an application instance
+$app = new Application(
+    new EventProvider(),
+    new ConfigProvider(),
+    Kiri::getContainer()
+);
+
+// Initialize the application
+$app->init();
+```
+
+### Configuration Management
+Configuration files can be loaded and accessed via the `ConfigProvider` class:
+```php
+$config = new ConfigProvider();
+$databaseHost = $config->get('database.host');
+```
+
+### Dependency Injection
+Use the container to inject dependencies:
+```php
+$service = Kiri::getContainer()->get(MyService::class);
+```
+
+### Logging
+Use the built-in logger to output messages:
+```php
+Kiri::getLogger()->info('This is an info message.');
+```
+
+### Exception Handling
+Register a custom exception handler:
+```php
+$errorHandler = new ErrorHandler();
+$errorHandler->registerExceptionHandler(function (Throwable $e) {
+    echo "Unhandled exception: " . $e->getMessage();
+});
+```
+
+### Database Connections
+
+#### Redis
+```php
+$redis = new Redis();
+$redis->connect();
+$redis->set('key', 'value');
+echo $redis->get('key');
+```
+
+#### MongoDB
+```php
+$mongo = new MongoDB();
+$collection = $mongo->getCollection('users');
+$result = $collection->find([]);
+```
+
+### Utility Class Examples
+
+#### String Operations
+```php
+echo Str::rand(10); // Generate a random string
+```
+
+#### JSON Response
+```php
+echo Json::jsonSuccess(['data' => 'example'], 'Operation successful');
+```
+
+#### Date Formatting
+```php
+echo DateFormat::DaySecond(); // Get the number of seconds in a day
+```
+

+# Kiri 核心框架文档
+
+## 项目介绍
+
+Kiri 是一个基于 PHP 的高性能核心框架，旨在为开发者提供简洁、高效的开发体验。该框架内置了多种实用工具类、异常处理机制、配置管理、容器依赖注入等功能，适用于构建各种类型的应用程序。
+
+### 主要特性
+- **依赖注入容器**：通过 `Kiri\Di\Container` 提供强大的依赖管理功能。
+- **配置管理**：支持从文件和环境变量中读取配置。
+- **异常处理**：提供统一的异常处理接口，支持注册自定义异常处理器。
+- **日志记录**：内置 `StdoutLogger` 支持多种日志级别输出。
+- **实用工具类**：
+  - `Str`：字符串操作，如加密、随机字符串生成等。
+  - `Json`：JSON 编码/解码及响应构造。
+  - `Help`：提供 XML 转换、随机数生成、邮件发送等辅助功能。
+  - `DateFormat`：日期和时间格式化工具。
+- **网络功能**：支持本地 IP 获取、Socket 编程。
+- **NoSQL 支持**：提供 Redis 和 MongoDB 的客户端封装，支持连接池管理。
+
+## 安装
+
+### 系统要求
+- PHP 7.4 或更高版本
+- Composer（用于依赖管理）
+
+### 安装步骤
+1. 确保已安装 Composer。
+2. 执行以下命令安装依赖：
+   ```bash
+   composer install
+   ```
+
+## 使用说明
+
+### 初始化框架
+```php
+use Kiri\Kiri;
+use Kiri\Application;
+
+// 初始化容器
+Kiri::setContainer(new Container());
+
+// 创建应用实例
+$app = new Application(
+    new EventProvider(),
+    new ConfigProvider(),
+    Kiri::getContainer()
+);
+
+// 初始化应用
+$app->init();
+```
+
+### 配置管理
+配置文件可通过 `ConfigProvider` 类进行加载和访问：
+```php
+$config = new ConfigProvider();
+$databaseHost = $config->get('database.host');
+```
+
+### 依赖注入
+使用容器进行依赖注入：
+```php
+$service = Kiri::getContainer()->get(MyService::class);
+```
+
+### 日志记录
+使用内置日志记录器输出信息：
+```php
+Kiri::getLogger()->info('This is an info message.');
+```
+
+### 异常处理
+注册自定义异常处理器：
+```php
+$errorHandler = new ErrorHandler();
+$errorHandler->registerExceptionHandler(function (Throwable $e) {
+    echo "Unhandled exception: " . $e->getMessage();
+});
+```
+
+### 数据库连接
+#### Redis
+```php
+$redis = new Redis();
+$redis->connect();
+$redis->set('key', 'value');
+echo $redis->get('key');
+```
+
+#### MongoDB
+```php
+$mongo = new MongoDB();
+$collection = $mongo->getCollection('users');
+$result = $collection->find([]);
+```
+
+### 工具类使用示例
+#### 字符串处理
+```php
+echo Str::rand(10); // 生成随机字符串
+```
+
+#### JSON 响应
+```php
+echo Json::jsonSuccess(['data' => 'example'], 'Operation successful');
