 ## Usage
 
 ### Importing Skeletons
 
-Use the **File** menu to select **Open** or **Batch Open** to import skeleton files.
+There are three ways to import skeleton files:
 
-### Adjusting Skeletons
+- 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.
 
-Select one or more items in the **Model List** to display adjustable parameters in the **Model Parameters** panel.
+### Adjusting Preview Content
 
-Right-clicking in the **Model List** allows you to add, delete, or adjust list items. You can also drag items with the left mouse button to rearrange them.
+The model list supports right-click menus and several hotkeys, and multiple models can be selected for batch adjustments of model parameters.
 
-### Adjusting the View
+In addition to using the control panel for parameter settings, the preview window supports the following mouse actions:
 
-Mouse operations supported in the **Preview** window:
+- 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.
 
-- Left-click to drag the skeleton
-- Right-click to drag the view
-- Scroll wheel to zoom in/out
+The buttons below the preview window allow you to adjust the timeline, effectively serving as a simple player.
 
-Additionally, you can adjust export and preview parameters through the **View Parameters** panel.
+### Exporting Preview Content
 
-In the **Functions** menu, you can reset and synchronize the animation time for all skeletons.
+Export follows the "What You See Is What You Get" principle—what you see in the live preview is exactly what gets exported.
 
-### Exporting Animations
+There are a few key parameters for exporting:
 
-Select **Export** from the **File** menu to export all loaded skeleton animations as PNG frame sequences, based on the current preview settings.
+- 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.
 
-You can view the full duration of each animation in the **Model Parameters** of each skeleton.
+### More Information
+
+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).

 ## 使用方法
 
 ### 骨骼导入
 
-**文件**菜单可以选择**打开**或者**批量打开**进行骨骼文件导入.
+有 3 种模式导入骨骼文件:
 
-或者直接把要打开的骨骼文件拖进列表, 这种方式只支持 `.json` 和 `.skel` 后缀的文件, 其他的会被忽略.
+- 拖放/粘贴需要导入的骨骼文件/目录到模型列表
+- 从文件菜单里批量打开骨骼文件
+- 从文件菜单选择单个模型打开
 
-### 骨骼调整
+### 预览内容调整
 
-在**模型列表**中选择一项或多项, 将会在**模型参数**面板显示可供调节的参数.
+模型列表支持右键菜单以及部分快捷键, 并且可以多选进行模型参数的批量调整.
 
-**模型列表**右键菜单可以对列表项进行增删调整, 也可以使用鼠标左键拖动调整顺序.
+预览画面除了使用面板进行参数设置外, 支持部分鼠标动作:
 
-### 画面调整
+- 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.
+- 右键对整体画面进行拖动.
+- 滚轮进行画面缩放.
+- 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.
 
-**预览画面**支持的鼠标操作:
+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.
 
-- 左键可以对骨骼进行拖动
-- 右键对画面进行拖动
-- 滚轮进行画面缩放
+### 预览内容导出
 
-除此之外, 也可以通过**画面参数**面板调节导出和预览时的画面参数.
+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.
 
-在**功能**菜单中, 可以重置同步所有骨骼动画时间.
+导出有以下几个关键参数:
 
-### 动画导出
+- 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.
 
-**文件**菜单中选择**导出**可以将目前加载的所有骨骼动画按照预览时的画面进行PNG帧序列导出.
+### 更多
 
-可以在每个骨骼的**模型参数**中查看动画完整时长.
+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).

+    Microsoft ResX Schema
+
+    Version 2.0
+
+    The primary goals of this format is to allow a simple XML format
+    that is mostly human readable. The generation and parsing of the
+    various data types are done through the TypeConverter classes
+    associated with the data types.
+
+    Example:
+
+    ... ado.net/XML headers & schema ...
+    <resheader name="resmimetype">text/microsoft-resx</resheader>
+    <resheader name="version">2.0</resheader>
+    <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
+    <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
+    <data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>
+    <data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
+    <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
+        <value>[base64 mime encoded serialized .NET Framework object]</value>
+    </data>
+    <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
+        <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
+        <comment>This is a comment</comment>
+    </data>
+
+    There are any number of "resheader" rows that contain simple
+    name/value pairs.
+
+    Each data row contains a name, and value. The row also contains a
+    type or mimetype. Type corresponds to a .NET class that support
+    text/value conversion through the TypeConverter architecture.
+    Classes that don't support this are serialized and stored with the
+    mimetype set.
+
+    The mimetype is used for serialized objects, and tells the
+    ResXResourceReader how to depersist the object. This is currently not
+    extensible. For a given mimetype the value must be set accordingly:
+
+    Note - application/x-microsoft.net.object.binary.base64 is the format
+    that the ResXResourceWriter will generate, however the reader can
+    read any of the formats listed below.
+
+    mimetype: application/x-microsoft.net.object.binary.base64
+    value   : The object must be serialized with
+            : System.Runtime.Serialization.Formatters.Binary.BinaryFormatter
+            : and then encoded with base64 encoding.
+
+    mimetype: application/x-microsoft.net.object.soap.base64
+    value   : The object must be serialized with
+            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter
+            : and then encoded with base64 encoding.
+
+    mimetype: application/x-microsoft.net.object.bytearray.base64
+    value   : The object must be serialized into a byte array
+            : using a System.ComponentModel.TypeConverter
+            : and then encoded with base64 encoding.
