+# @github/spark
+
+Spark runtime and hooks for low-code React applications.
+
+## Overview
+
+The `@github/spark` package provides core functionality for Spark-powered applications:
+
+- **useKV Hook**: Persistent key-value storage with localStorage and Spark KV integration
+- **Spark Runtime**: Mock LLM service, KV storage, and user authentication APIs
+- **Vite Plugins**: Build-time integrations for Spark applications
+
+## Installation
+
+This package is designed to be used as a workspace dependency:
+
+```json
+{
+  "dependencies": {
+    "@github/spark": "workspace:*"
+  }
+}
+```
+
+## Usage
+
+### useKV Hook
+
+The `useKV` hook provides persistent state management:
+
+```typescript
+import { useKV } from '@github/spark/hooks'
+
+function MyComponent() {
+  const [count, setCount, deleteCount] = useKV('counter', 0)
+  
+  return (
+    <div>
+      <p>Count: {count}</p>
+      <button onClick={() => setCount(count + 1)}>Increment</button>
+      <button onClick={deleteCount}>Reset</button>
+    </div>
+  )
+}
+```
+
+### Spark Runtime
+
+Initialize the Spark runtime in your application entry point:
+
+```typescript
+import '@github/spark/spark'
+```
+
+Access the runtime APIs:
+
+```typescript
+// KV Storage
+window.spark.kv.set('key', 'value')
+const value = window.spark.kv.get('key')
+
+// LLM Service
+const response = await window.spark.llm.chat([
+  { role: 'user', content: 'Hello!' }
+])
+
+// User Info
+const user = window.spark.user.getCurrentUser()
+```
+
+### Vite Plugins
+
+Add Spark plugins to your Vite configuration:
+
+```typescript
+import sparkPlugin from '@github/spark/spark-vite-plugin'
+import createIconImportProxy from '@github/spark/vitePhosphorIconProxyPlugin'
+
+export default defineConfig({
+  plugins: [
+    sparkPlugin(),
+    createIconImportProxy()
+  ]
+})
+```
+
+## API Reference
+
+### useKV<T>(key: string, defaultValue: T)
+
+Returns: `[value: T, setValue: (value: T | ((prev: T) => T)) => void, deleteValue: () => void]`
+
+- `key`: Storage key
+- `defaultValue`: Default value if key doesn't exist
+- `value`: Current value
+- `setValue`: Update the value (supports functional updates)
+- `deleteValue`: Delete the value and reset to default
+
+### window.spark
+
+Global runtime object with the following APIs:
+
+- `kv.get(key)`: Get value from KV storage
+- `kv.set(key, value)`: Set value in KV storage
+- `kv.delete(key)`: Delete key from KV storage
+- `kv.clear()`: Clear all KV storage
+- `kv.keys()`: Get all keys
+- `llm.chat(messages)`: Chat with LLM
+- `llm.complete(prompt)`: Complete a prompt
+- `user.getCurrentUser()`: Get current user info
+- `user.isAuthenticated()`: Check if user is authenticated
