 Runed is a collection of utilities for Svelte 5 that make composing powerful applications and
 libraries a breeze, leveraging the power of [Svelte Runes](https://svelte.dev/blog/runes).
+
+## Why Runed?
+
+Svelte 5 Runes unlock immense power by providing a set of primitives that allow us to build
+impressive applications and libraries with ease. However, building complex applications often
+requires more than just the primitives provided by Svelte Runes.
+
+Runed takes those primitives to the next level by providing:
+
+- **Powerful Utilities**: A set of carefully crafted utility functions and classes that simplify
+  common tasks and reduce boilerplate.
+- **Collective Efforts**: We often find ourselves writing the same utility functions over and over
+  again. Runed aims to provide a single source of truth for these utilities, allowing the community
+  to contribute, test, and benefit from them.
+- **Consistency**: A consistent set of APIs and behaviors across all utilities, so you can focus on
+  building your projects instead of constantly learning new APIs.
+- **Reactivity First**: Powered by Svelte 5's new reactivity system, Runed utilities are designed to
+  handle reactive state and side effects with ease.
+- **Type Safety**: Full TypeScript support to catch errors early and provide a better developer
+  experience.
+
+## Ideas and Principles
+
+#### Embrace the Magic of Runes
+
+Svelte Runes are a powerful new paradigm. Runed fully embraces this concept and explores its
+potential. Our goal is to make working with Runes feel as natural and intuitive as possible.
+
+#### Enhance, Don't Replace
+
+Runed is not here to replace Svelte's core functionality, but to enhance and extend it. Our
+utilities should feel like a natural extension of Svelte, not a separate framework.
+
+#### Progressive Complexity
+
+Simple things should be simple, complex things should be possible. Runed provides easy-to-use
+defaults while allowing for advanced customization when needed.
+
+#### Open Source and Community Collaboration
+
+Runed is an open-source, MIT licensed project that welcomes all forms of contributions from the
+community. Whether it's bug reports, feature requests, or code contributions, your input will help
+make Runed the best it can be.
