+封面图生成工具
+===
+
+### 依赖
+Python3
+PIL (Pillow)
+
+### 安装依赖
+安装 Python： <https://docs.python.org/zh-cn/3.7/using/index.html>
+安装 PIL：
+
+```bash
+# Linix/Mac Terminal
+pip install Pillow
+# 如果也安装了 Python 2，需要指定 pip 版本：
+pip3 install Pillow
+
+# Windows Powershell 或者 CMD
+pip install Pillow
+# 如果也安装了 Python 2，需要指定 pip 版本：
+pip3 install Pillow
+# 如果提示权限不足（[WinError 5] Access is denied），请运行：
+pip install Pillow --user
+```
+
+### 运行
+把图片文件放到 `gallary` 目录，Windows 可直接双击 main.py，或者和其他操作系统一样，在 Terminal、Powershell、CMD 中运行：
+
+```bash
+# 切换到 main.py 所在目录：
+cd /path/to/manifest/
+python main.py
+# 如果也安装了 Python 2，需要指定 pip 版本：
+python3 main.py
+```
+
+### TODO
+自动删除过期文件、压缩图片、GitHub API push、release
