-PHP: 网页实现
+## 项目简介
-Json: 存储工具集
 
-### 部署
+SecHub 是一个面向网络安全领域的工具集合系统，提供多种网络安全工具的集中管理。该项目采用 JSON 存储工具信息，通过 PHP 网页界面实现工具的展示与访问，为安全研究人员和从业者提供一站式的工具导航平台。
 
-直接复制本项目放置于服务器上即可
+## 功能特性
+
+- 🛠️ **工具分类管理**：按类别组织网络安全工具，便于查找和使用
+- 🔍 **智能搜索**：支持全局搜索和栏目内搜索，快速定位所需工具
+- 🌓 **主题切换**：支持白天/黑夜模式切换，保护视力
+- 📱 **响应式设计**：适配各种屏幕尺寸，移动端友好
+- 💾 **数据持久化**：使用 SQLite 数据库存储工具信息，提高查询效率
+- 🔄 **自动同步**：JSON 数据变更时自动同步到数据库
+- 📥 **数据导出**：支持下载原始 JSON 数据文件
+
+## 技术栈
+
+- **后端**: PHP
+- **数据库**: SQLite
+- **前端**: HTML, CSS, JavaScript
+- **数据存储**: JSON 文件
+- **架构**: JSON 驱动架构

+
+## 部署方式
+
+### 环境要求
+
+- PHP 7.0+
+- PDO SQLite 扩展
+- Web 服务器（Apache/Nginx）
+
+### 快速部署
+
+1. 克隆或下载本项目
+2. 将项目文件放置于 Web 服务器根目录
+3. 确保 `assets/db/` 目录具有写入权限
+4. 访问 `index.php` 即可使用
+
+### 权限设置
+
+确保以下目录具有写入权限：
+```bash
+chmod 755 assets/db/
+```
+
+## 使用说明
+
+### 添加新工具
+
+在对应的 JSON 文件中添加工具信息，格式如下：
+
+```json
+[
+    {
+        "section": "安全工具"
+    },
+    {
+        "name": "工具名称",
+        "url": "https://example.com",
+        "description": "工具描述"
+    }
+]
+```
+
+### 搜索功能
+
+- **全局搜索**：在顶部搜索框输入关键词，实时显示所有栏目中的匹配结果
+- **栏目搜索**：在每个栏目内的搜索框输入关键词，仅在该栏目中搜索
+
+### 主题切换
+
+点击右上角的月亮/太阳图标切换白天/黑夜模式，系统会记住您的选择。
+
+## 数据格式
+
+每个 JSON 文件包含一个数组，第一个元素定义栏目名称，后续元素为具体的工具信息：
+
+```json
+[
+    {
+        "section": "栏目名称"
+    },
+    {
+        "name": "工具名称",
+        "url": "工具链接",
+        "description": "工具描述"
+    }
+]
+```
+
+## 核心功能说明
+
+### 数据库同步机制
+
+系统采用智能同步机制，仅在 JSON 文件修改时间超过 5 分钟时才更新数据库，避免频繁读写影响性能。
+
+### 搜索算法
+
+支持对工具名称、描述和 URL 进行模糊搜索，提供实时的搜索结果反馈。
+
+### 响应式设计
+
+采用现代 CSS Grid 布局，自动适配不同屏幕尺寸，提供良好的移动端体验。
