+# 快速打开电子教材
+
+## 简介
+
+用于在课堂上快速打开电子教材，支持多科目和多教材。
+
+
+## 文件结构
+- `main.py`：主程序文件，包含所有的界面和功能实现。
+- `config.json`：配置文件，存储科目及其对应的教材文件路径。
+
+## 依赖项
+- Python 3.x
+- PySide6
+
+## 安装
+1. 安装 Python 3.x。
+2. 安装 PySide6：
+    ```bash
+    pip install PySide6
+    ```
+3. 克隆或下载此项目。
+
+## 使用
+1. 确保 `config.json` 配置文件存在，并且格式如下：
+    ```json
+    {
+        "科目1": {
+            "教材1": "路径/到/文件1",
+            "教材2": "路径/到/文件2"
+        },
+        "科目2": {
+            "教材1": "路径/到/文件1",
+            "教材2": "路径/到/文件2"
+        }
+    }
+    ```
+2. 运行主程序：
+    ```bash
+    python main.py
+    ```
+3. 点击圆形按钮打开主界面，选择科目并点击相应按钮打开文件。
+
+## 配置文件
+`config.json` 是一个 JSON 格式的配置文件，用于存储科目及其对应的教材文件路径。示例如下：
+```json
+{
+    "数学": {
+        "代数": "C:/教材/数学/代数.pdf",
+        "几何": "C:/教材/数学/几何.pdf"
+    },
+    "物理": {
+        "力学": "C:/教材/物理/力学.pdf",
+        "电学": "C:/教材/物理/电学.pdf"
+    }
+}
+```
+
+## 注意事项
+
+- 确保配置文件中的路径是有效的文件路径。
+- 运行程序时需要保证 `config.json` 文件位于与 `main.py` 相同的目录下。
