+## Installation
+
+1. Go to the [Releases](https://github.com/ww-rm/SpineViewer/releases) page and download the ZIP.  
+2. Make sure you have the [.NET Desktop Runtime 8.0.x](https://dotnet.microsoft.com/download/dotnet/8.0) installed.  
+3. Alternatively, download the `SelfContained` ZIP, which runs standalone without any .NET prerequisites.  
+4. To export GIF or other video formats, install the `ffmpeg` CLI and add it to your PATH.  
+   - Windows builds: see the [FFmpeg download page](https://ffmpeg.org/download.html#build-windows)  
+   - Direct download: [ffmpeg-release-full.7z](https://www.gyan.dev/ffmpeg/builds/ffmpeg-release-full.7z)
+
+## Usage
+
+### Importing Skeletons
+
+You can import Spine skeletons in three ways:
+
+- Drag & drop or paste skeleton files or folders onto the model list.  
+- Use **File > Open** to batch‑open multiple skeleton files.  
+- Use **File > Open Single Model** to open one at a time.
+
+### Adjusting Content
+
+- Right‑click menu and keyboard shortcuts are available in the model list. You can multi‑select to adjust parameters in batch.  
+- In the preview pane, you can also use mouse controls:
+  - **Left‑click & drag** to move a model; hold **Ctrl** to multi‑select (synced with the list).  
+  - **Right‑click & drag** to pan the entire scene.  
+  - **Mouse wheel** to zoom; hold **Ctrl** to zoom all selected models proportionally.  
+  - **“Render Selected Only”** mode shows only the selected models in preview; use the list to change selection.
+
+Below the preview, playback controls let you scrub through the timeline like a basic player.
+
+### Exporting Content
+
+Exports follow the “what you see is what you get” principle—your real‑time preview is exactly what gets exported.
+
+Key export options:
+
+- **Render Selected Only**: includes only the selected models in both preview and export.  
+- **Output Folder**: if unspecified, exports go into each model’s source folder; otherwise, everything exports to the chosen folder.  
+- **Export Single**: by default, each model is exported separately; enable this to render all selected models together into a single output.  
+- **Auto Resolution**: ignores preview resolution and viewport size—exports at the content’s actual bounds; for animations, matches the full animation area.
+

 ## 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 种方式导入骨骼文件:
 
-### 骨骼调整
+- 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
 
-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.
+### 内容调整
 
-**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.
+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.
 
-### 画面调整
+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:
 
-**预览画面**支持的鼠标操作:
+- 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, 按住 `Ctrl` 可以对选中的模型进行批量缩放.
+- 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.
 
-- 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.
 
-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.
+### 内容导出
 
-在**功能**菜单中, 可以重置同步所有骨骼动画时间.
+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.
 
-### 动画导出
+导出有以下几个关键参数:
 
-**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.
+- 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.
+- 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.
 
-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="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>

+        <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.
+

+    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.

+    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.

+    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.
