+# N0vaResourceExtractor
+## 这是什么
+提取`人工桌面（米哈游旗下一款动态壁纸软件）`的动态壁纸资源的工具。
+## 如何使用
+### 如果需要批量拆资源文件
+直接把二进制文件复制到人工桌面的安装目录然后运行即可。生成的文件为`源文件_changed.mp4`
+### 如果需要单个替换
++ Linux：输入 `./N0vaResourceExtractor [需要替换的文件]
++ Windows: 直接把ndf文件拖到二进制文件里即可
+## 从源代码构建
+### Linux:(安装cmake和gcc环境)
+```
+mkdir build
+cd build
+cmake ..
+make
+```
+在`build`目录下寻找产出的二进制文件
+### Windows(安装cmake和MinGW-W64)
+```
+mkdir build
+cd build
+cmake -G "MinGW Makefiles" ..
+mingw32-make
+```
+在`build`目录下寻找产出的二进制文件
+## 开源
+本项目使用MIT协议开源。模型为米哈游版权所有。
