 ## 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.
+### More Information
 
-### Format & Version Conversion
+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.
+## Acknowledgements
 
-Currently under development, it only supports converting `3.8.x` binary format to text format.

 ### 骨骼导入
@@ -40,21 +54,8 @@
 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
-
-    这种方式会自动查找传入的文件列表以及目录内的子级文件列表, 虽然方便但是依赖模型文件结构, 限制最多.
-
-    - 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.
-- 选择单个模型打开
-
-    这种方式自由度最高, 允许选择任意的骨骼文件和 atlas 文件, 可以没有文件名限制, 并且也可以设置加载版本.
+- 从文件菜单选择单个模型打开

 - 左键可以选择和拖拽模型, 按下 `Ctrl` 键可以实现多选, 与左侧列表选择是联动的.

+- 仅渲染选中模式, 在该模式下, 预览画面仅包含被选中的模型, 并且只能通过左侧列表改变选中状态.
 
-在功能菜单中, 可以重置同步所有骨骼动画时间.
+预览画面下方按钮支持对画面时间进行调整, 可以当作一个简易的播放器.
 
 ### 预览内容导出
 
-支持预览图和视频的导出.
+导出遵循 "所见即所得" 原则, 即实时预览的画面就是你导出的画面.
 
-预览图导出的内容是模型的默认状态画面, 每个模型一张单独的预览图.
+导出有以下几个关键参数:
 
-视频(TODO: 目前仅支持帧序列导出), 可以在每个骨骼的模型参数中查看动画完整时长.
+- 仅渲染选中. 这个参数不仅影响预览模式, 也影响导出, 如果仅渲染选中, 那么在导出时只有被选中的模型会被考虑, 忽略其他模型.
+- 输出文件夹. 这个参数某些时候可选, 当不提供时, 则将输出产物输出到每个模型各自的模型文件夹, 否则输出产物全部输出到提供的输出文件夹.
+- 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.
 
-当预览画面处于仅渲染选中状态时, 导出的内容仅包含被选中的模型, 也就是在画面中显示的内容.

-### 格式与版本转换
+更为详细的使用方法和说明见 [Wiki](https://github.com/ww-rm/SpineViewer/wiki), 有使用上的问题或者 BUG 可以提个 [Issue](https://github.com/ww-rm/SpineViewer/issues).
 
-可以通过工具菜单进行骨骼文件转换, 允许二进制和文本格式之间的转换, 以及不同版本间的转换.
