- **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.
+More versions are under development :rocket: :rocket: :rocket:

- **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.
+## How to Use

- **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.
+### Importing Skeleton Files

-### Adjusting Preview Content
+There are three ways to import skeleton files:

-The model list supports right-click menus and various shortcut keys, and you can select multiple models to adjust their parameters in bulk.
+- Drag and drop or paste the skeleton file/directory into the model list.
+- Batch open skeleton files from the File menu.
+- Select a single model to open from the File menu.

-In addition to the parameter panel, the preview area supports several mouse actions:
+### Adjusting the Preview

- **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.
+The model list supports context menus and some shortcuts, and you can multi-select to adjust parameters in bulk.

-In the function menu, you can reset and synchronize the animation time for all skeletons.
+In addition to using the panel for parameter settings, the preview screen supports several mouse actions:

-### Exporting Preview Content
+- 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 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.

-Both preview images and videos can be exported.
+The buttons below the preview allow you to adjust the timeline, acting as a simple media player.

- **Preview Image:**  
-  The exported preview image shows the model in its default state, with one image per model.
-  
- **Video (TODO: Currently only supports frame sequence export):**  
-  The complete animation duration for each skeleton can be viewed in the model parameters.
-  
-When the preview area is set to render only the selected models, the exported content will include only the models that are displayed.
+### Exporting the Preview

-### Format & Version Conversion
+Exporting follows the “What You See Is What You Get” principle – the preview exactly reflects the output.

-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.
+There are several key parameters for export:

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