-A collection of tools I've built to **make web development simpler.**
+Simple Stack is a collection of lightweight, focused tools for Astro and web development. Each package solves a single use case well, without unnecessary complexity.
 
-To be honest, there isn't a "story" connecting these packages together (I'm no TanStack). But they follow a common theme: solve a simple use case without too many features.
+Packages include **Simple Store** (reactive state management), **Simple Scope** (build-time scoped IDs), and **Simple Query** (DOM querying for Astro components).
