+# nychthemeron
+
+A CSS-reactive Vue component library built on PrimeVue (Unstyled), shipped with the nychthemeron theme as a default.
+
+## About
+
+nychthemeron provides a curated set of Vue 3 components powered by PrimeVue's unstyled components and the nychthemeron theme system. This approach gives you complete control over component styling while maintaining a consistent, polished design language out of the box.
+
+### Features
+
+- **CSS-Reactive**: Components respond to CSS changes without requiring JavaScript updates
+- **PrimeVue Powered**: Built on the robust, accessible PrimeVue unstyled component library
+- **Theme Included**: Ships with the nychthemeron theme, ready to use immediately
+- **TypeScript**: Full type support for Vue 3 and TypeScript projects
+- **Customizable**: Override or extend the default theme to match your design system
+
+## Quick Start
+
+### Installation
+
+```bash
+npm install @nychthemeron/library primevue vue@^3.5.0
+```
+
+### Basic Usage
+
+Import the library components and styles:
+
+```vue
+<script setup lang="ts">
+import { NychButton } from '@nychthemeron/library'
+</script>
+
+<template>
+  <NychButton label="Click me" />
+</template>
+
+<style>
+@import '@nychthemeron/library/style';
+@import '@nychthemeron/library/theme';
+</style>
+```
+
+## Components
+
+- **NychButton** - Customizable button component
+
+More components coming soon.
+
+## Customization
+
+### Using the Default Theme
+
+The nychthemeron theme is included by default:
+
+```css
+@import '@nychthemeron/library/theme';
+```
+
+### Custom Styling
+
+Override or extend component styles by importing only the base styles and providing your own CSS:
+
+```css
+@import '@nychthemeron/library/style';
+
+/* Your custom theme */
+:root {
+  --primary-color: #your-color;
+  /* More CSS variables */
+}
+```
+
+## Project Structure
+
+This is a monorepo containing:
+
+- **`packages/library`** - The component library package
+- **`packages/playground`** - Development environment and examples
+
+## Development
+
+### Setup
+
+```bash
+bun install
+```
+
+### Development Server
+
+Start the playground to develop and test components:
+
+```bash
+bun dev
+```
+
+### Build
+
+Build the library for production:
+
+```bash
+bun build
+```
+
+### Testing
+
+Run unit tests:
+
+```bash
+bun test
+```
+
+### Linting and Formatting
+
+```bash
+bun lint       # Check and fix linting issues
+bun format     # Format code with Prettier
+bun type-check # Run TypeScript type checking
+```
+
+## Requirements
+
+- **Node.js**: >=20.19.0 or >=22.12.0
+- **Vue**: ^3.5.0
+- **PrimeVue**: ^4.5.0
+
+## Browser Support
