+### Dynamic Wallpaper
+
+Dynamic wallpaper is implemented through desktop projection, allowing the content of the current preview to be projected onto the desktop in real time.
+
+You can enable or disable desktop projection from the program preferences or the right-click menu of the tray icon. After adjusting the model and display parameters, you can save the current configuration as a workspace file for convenient restoration later.
+
+If you want the wallpaper to stay active after startup, you can enable auto-start in the preferences and specify which workspace file should be loaded when the program launches.

 - 导出单个. 默认是每个模型独立导出, 即对模型列表进行批量操作, 如果选择仅导出单个, 那么被导出的所有模型将在同一个画面上被渲染, 输出产物只有一份.
 - 自动分辨率. 该模式会忽略预览画面的分辨率和视区参数, 导出产物的分辨率与被导出内容的实际大小一致, 如果是动图或者视频则会与完整显示动画的必需大小一致.
 
+### 动态壁纸
+
+动态壁纸通过桌面投影实现, 可以将当前预览画面上的内容实时投影至桌面.
+
+在程序首选项或者托盘图标右键菜单中可以进行桌面投影的启用与否, 模型和画面参数调整完成后, 可以将当前参数保存为工作区文件, 方便之后恢复该配置.
+
+如果希望开机自启常驻壁纸, 也可以在首选项中启用开机自启, 并且设置启动后需要加载的工作区文件.
