-## Usage
+## How to Use

-### Importing Skeletons
+### Importing Skeleton Files

 There are three ways to import skeleton files:

 - Drag and drop or paste the skeleton file/directory into the model list.
- Open skeleton files in batch from the File menu.
+- Batch open skeleton files from the File menu.
 - Select a single model to open from the File menu.

-### Adjusting Preview Content
+### Adjusting the Preview

-The model list supports right-click menus and several hotkeys, and multiple models can be selected for batch adjustments of model parameters.
+The model list supports context menus and some shortcuts, and you can multi-select to adjust parameters in bulk.

-In addition to using the control panel for parameter settings, the preview window supports the following mouse actions:
+In addition to using the panel for parameter settings, the preview screen supports several mouse actions:

- 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.
+- Left-click to select and drag models; hold the `Ctrl` key for multi-selection (which is synchronized with the 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.
+- Use the mouse wheel to zoom in and out.
+- “Render Selected” mode: in this mode, the preview screen only shows the selected models and the selection state can only be changed from the list on the left.

-The buttons below the preview window allow you to adjust the timeline, effectively serving as a simple player.
+The buttons below the preview allow you to adjust the timeline, acting as a simple media player.

-### Exporting Preview Content
+### Exporting the Preview

-Export follows the "What You See Is What You Get" principle—what you see in the live preview is exactly what gets exported.
+Exporting follows the “What You See Is What You Get” principle – the preview exactly reflects the output.

-There are a few key parameters for exporting:
+There are several key parameters for export:

- 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.
+- Render Selected Only: This option affects both the preview and export. If enabled, only the selected models will be considered during export while ignoring the others.
+- Output Folder: This parameter is optional in some cases. If not provided, the output files will be saved in each model’s own folder; otherwise, all outputs will be saved to the specified folder.
+- Single Export: By default, each model is exported separately (i.e., batch operation on the model list). If “Single Export” is selected, all the exported models will be rendered on the same canvas, producing only one output file.

+  <!--
+    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.

+    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>

+        <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.
