+# Pulse Editor Core
+
+## One Codebase, Every Platform
+Pulse Editor Core is developed using modern web technologies with Next.js, enabling a single codebase for all platforms. Its architecture is built around abstract interfaces, allowing native-specific implementations to plug in cleanly while maintaining a consistent core logic.
+
+## Native Support via Electron and Capacitor
+After the app is built with Next.js, it is deployed to native platforms using Electron for desktop and Capacitor for mobile. This setup enables full native functionality across devices while preserving the benefits of a unified codebase.
