 # MarkdownLivePreview
 
+## Acknowledgments
+
+This project is a fork of [MarkdownLivePreview](https://github.com/math2001/MarkdownLivePreview) by **math2001**. I'm grateful for the original implementation, which provided a solid foundation for live Markdown preview in Sublime Text.
+
+Many thanks to math2001 for the original code—this fork wouldn't have been possible without their work.
+
+## Changes contained in this Fork
+
+In this fork ([christian.morpurgo/MarkdownLivePreview](https://git.0x42.cloud/christian.morpurgo/MarkdownLivePreview)), I've made the following enhancements:
+
+- **Bundled `bs4` and `soupsieve`**  
+  Repackaged both libraries as standalone modules by rewriting their imports, resolving errors when Sublime Text 4 attempted to install these old versions as external dependencies.
+
+- **`font_scale` option**  
+  Added a new `font_scale: number` setting to allow users to increase or decrease the preview text size directly from their Sublime Text settings.
+
+- **In-window preview**  
+  Changed the preview behavior so that starting a preview reuses the current window instead of opening a new one.
+
+
 A simple plugin to preview your markdown as you type right in Sublime Text.
 No dependencies!
