 This will start a local Streamlit server and automatically open the application in your default web browser at `http://localhost:8501/`. From there, you can:
 - Upload game files
 - Tinker with formatting options (e.g., node size, layouts, colors, label backgrounds)
-- Download the resulting Tex, SVG, PDF, or PNG images.
+- Download the resulting Tex, SVG, PDF, or PNG images, as well as the active rendering configuration.

+## Exporting and Reusing Settings
+
+When you adjust the visual styling of a game in the GUI, you can export these configuration parameters by clicking the **Settings** button in the **Downloads** pane. This downloads a YAML file containing all active styling options (e.g., color schemes, spacing, custom fonts, label offsets).
+
+### Integration with the Gambit Game Catalog
+
+If you are a Gambit developer adding new games to the official game catalog, you can use the exported YAML settings to specify how these games should render by default. To do this:
+
+1. Download the styling configuration file using the **Settings** button.
+2. Copy the game's configuration section from the downloaded YAML.
+3. Paste or append the configuration under the appropriate key in the master settings file in the Gambit repository: [build_support/catalog/draw_tree_settings.yaml](https://github.com/gambitproject/gambit/blob/master/build_support/catalog/draw_tree_settings.yaml).
+
+Once added, the game will automatically use your custom styles when displayed in the catalog.
