 ## Usage
 
 ### Importing Skeletons
 
-There are 3 ways to import skeleton files:
+There are three ways to import skeleton files:
 
-- **Drag & Drop/Paste:**  
-  Drag and drop or paste the skeleton file/directory into the model list.  
-  This method automatically searches through the provided files and subdirectories. Although convenient, it relies on the file structure and has its limitations.
-  
-  - Only standard files with `*.json`, `*.skel`, or `.atlas` extensions are automatically detected.
-  - The skeleton file and atlas file must have the same name.
-  - The version string in the skeleton file must not be modified.
-
-- **Batch Open from the File Menu:**  
-  This method offers more file flexibility. You can drag and drop or paste files into the file selection dialog, and additional options are available.
-  
-  - The filename restrictions are similar to the above, but you can use the panel’s file selection button to choose skeleton files with non-standard extensions.
-  - You can set a fixed load version to handle cases where the version number has been modified.
-
-- **Open a Single Model:**  
-  This method offers the highest degree of freedom, allowing you to select any skeleton file and atlas file without filename restrictions. You can also set the load version.
+- Drag and drop or paste the skeleton file/directory into the model list.
+- Open skeleton files in batch from the File menu.
+- Select a single model to open from the File menu.
 
 ### Adjusting Preview Content
 
-The model list supports right-click menus and various shortcut keys, and you can select multiple models to adjust their parameters in bulk.
+The model list supports right-click menus and several hotkeys, and multiple models can be selected for batch adjustments of model parameters.
 
-In addition to the parameter panel, the preview area supports several mouse actions:
+In addition to using the control panel for parameter settings, the preview window supports the following mouse actions:
 
-- **Left-click:** Select and drag models. Holding down the `Ctrl` key enables multi-selection, which syncs with the model list.
-- **Right-click:** Drag the overall canvas.
-- **Scroll wheel:** Zoom the view.
-- **Selective Rendering:** The preview area supports a mode to render only the selected models. In this mode, only the selected models are displayed, and selection changes must be made through the model list.
+- Left-click to select and drag models. Hold the `Ctrl` key to enable multi-selection, which is synchronized with the model list on the left.
+- Right-click to drag the overall view.
+- Use the scroll wheel to zoom in/out.
+- "Render selected only" mode, in which the preview only includes selected models and the selection can only be changed via the model list on the left.
 
-In the function menu, you can reset and synchronize the animation time for all skeletons.
+The buttons below the preview window allow you to adjust the timeline, effectively serving as a simple player.
 
 ### Exporting Preview Content
 
-Both preview images and videos can be exported.
+Export follows the "What You See Is What You Get" principle—what you see in the live preview is exactly what gets exported.
 
-- **Preview Image:**  
-  The exported preview image shows the model in its default state, with one image per model.
+There are a few key parameters for exporting:
 
-- **Video (TODO: Currently only supports frame sequence export):**  
-  The complete animation duration for each skeleton can be viewed in the model parameters.
+- Render Selected Only: This option not only affects the preview mode but also the export; if enabled, only the selected models will be considered, and all other models will be ignored during export.
+- Output Folder: This parameter is optional in some cases. If not provided, the output will be saved in each model's own directory. Otherwise, all output files will be saved to the specified folder.
+- Single Export: By default, each model is exported individually in batch mode. If "Single Export" is selected, all exported models will be rendered on a single canvas, resulting in only one output file.
 
-When the preview area is set to render only the selected models, the exported content will include only the models that are displayed.

+For more detailed instructions and usage, please refer to the [Wiki](https://github.com/ww-rm/SpineViewer/wiki). If you encounter any issues or bugs, please open an [Issue](https://github.com/ww-rm/SpineViewer/issues).
 
-You can use the tools menu to convert skeleton files. This feature supports conversion between binary and text formats, as well as between different versions.

-Currently under development, it only supports converting `3.8.x` binary format to text format.

 有 3 种模式导入骨骼文件:
 
 - 拖放/粘贴需要导入的骨骼文件/目录到模型列表

-
-    - 仅支持自动发现标准的 `*.json`/`*.skel`/`.atlas` 后缀文件.
-    - 骨骼文件和 atlas 文件需要是同名.
-    - 需要保证骨骼文件里的版本字符串不是魔改过的.
 - 从文件菜单里批量打开骨骼文件
-
-    这种方式提供一定程度的文件自由度, 文件选择框里同样支持拖放/粘贴, 但是多一些额外选项.
-
-    - 文件名限制条件与上面类似, 但是可以通过面板的选择文件按钮选择非标准后缀的骨骼文件.
-    - 可以设置固定加载版本, 便于应对魔改过的版本号.
