+```
+
+## CLI
+
+The `brownie` CLI generates native store types from TypeScript schema.
+
+### Usage
+
+```bash
+brownie codegen                   # Generate for all configured platforms
+brownie codegen -p swift          # Generate Swift only
+brownie codegen --platform kotlin # Generate Kotlin only
+brownie --help                    # Show help
+brownie --version                 # Show version
+```
+
+### Configuration
+
+Add to your app's `package.json`:
+
+```json
+{
+  "brownie": {
+    "swift": "./ios/Generated/",
+    "kotlin": "./android/app/src/main/java/com/example/",
+    "kotlinPackageName": "com.example"
+  }
+}
+```
+
+| Field               | Required | Description                               |
+| ------------------- | -------- | ----------------------------------------- |
+| `swift`             | No\*     | Output directory for Swift files          |
+| `kotlin`            | No\*     | Output directory for Kotlin files         |
+| `kotlinPackageName` | No       | Kotlin package name (extracted from path) |
+
+\*At least one of `swift` or `kotlin` is required.
+
+### Store Definition
+
+Stores are auto-discovered from `*.brownie.ts` files. Define your store shape using module augmentation:
+
+```ts
+// BrownfieldStore.brownie.ts
+import type { BrownieStore } from '@callstack/brownie';
+
+interface BrownfieldStore extends BrownieStore {
+  counter: number;
+  user: string;
+  isLoading: boolean;
+}
+
+declare module '@callstack/brownie' {
+  interface BrownieStores {
+    BrownfieldStore: BrownfieldStore;
+  }
+}
+```
+
+Multiple stores in same file:
+
+```ts
+// Stores.brownie.ts
+import type { BrownieStore } from '@callstack/brownie';
+
+interface UserStore extends BrownieStore {
+  name: string;
+  email: string;
+}
+
+interface SettingsStore extends BrownieStore {
+  theme: 'light' | 'dark';
+  notificationsEnabled: boolean;
+}
+
+declare module '@callstack/brownie' {
+  interface BrownieStores {
+    UserStore: UserStore;
+    SettingsStore: SettingsStore;
+  }
+}
+```
+
+### Generated Output
+
+**Swift** (`Codable` struct with mutable properties):
+
+```swift
+struct BrownfieldStore: Codable {
+    var counter: Double
+    var isLoading: Bool
+    var user: String
+}
+```
+
+**Kotlin** (data class):
+
+```kotlin
+package com.example
+
+data class BrownfieldStore (
+    val counter: Double,
+    val isLoading: Boolean,
+    val user: String
+)
+```
+
+## CLI Implementation
+
+### File Structure
+
+```

+├── cli.ts              # Entry point, parseArgs, command routing
+├── config.ts           # Config loading from package.json

+└── generators/
+    ├── swift.ts        # Swift Codable generation
+    └── kotlin.ts       # Kotlin data class generation
+```
+
+### Store Discovery
+
+1. Recursively finds `*.brownie.ts` files (skips node_modules)
+2. Parses `declare module '@callstack/brownie'` blocks using ts-morph
+3. Extracts store names from `BrownieStores` interface properties
+4. Validates no duplicate store names exist
+
+### Codegen Pipeline
+
+```

+       │
+       └──▶ Kotlin (lang: 'kotlin', framework: 'just-types')
+```
+
+### Build
+
+Scripts are compiled with TypeScript during package build:
+
+```bash
+yarn build  # runs bob build && tsc -p scripts/tsconfig.json
+```
+
+Output goes to `lib/scripts/` and is exposed via `bin` field in `package.json`.

+### C++ Core
+
+**BrownieStore** - Thread-safe store with `folly::dynamic` as source of truth:
+
+- `get(key)` - Get property by key
+- `set(key, value)` - Set property, triggers change callback
+- `getSnapshot()` - Get full state
+- `setState(state)` - Replace entire state
+- `setChangeCallback(cb)` - Register callback for changes
+- All operations protected by `std::mutex`
+
+**BrownieStoreManager** - Singleton registry:
+
+- `shared()` - Get singleton instance
+- `registerStore(key, store)` - Register store
+- `getStore(key)` - Retrieve store
+- `removeStore(key)` - Cleanup store
+
+**BrownieHostObject** - JSI bridge:
+
+- `get(prop)` - Read property, converts `folly::dynamic` → `jsi::Value`
+- `set(prop, value)` - Write property, converts `jsi::Value` → `folly::dynamic`
+- `unbox()` - Returns full state snapshot as JSI object
+- `getPropertyNames()` - Returns list of all property names
+- Uses built-in `jsi::valueFromDynamic`/`jsi::dynamicFromValue` converters
+
+### iOS Bridge
+
+**BrownieStoreBridge** (ObjC++) - Exposes C++ to Swift:
+
+- `registerStore(withKey:)` - Create C++ store, set up notification callback
+- `removeStore(withKey:)` - Cleanup
+- `setValue(_:forKey:inStore:)` - Set property
+- `getValue(forKey:inStore:)` - Get property
+- `getSnapshot(forStore:)` - Get full state as NSDictionary
+- `setState(from:forStore:)` - Set full state from NSDictionary
+- Posts `BrownieStoreUpdated` notification with `storeKey` in userInfo
+
+### Swift Layer
+
+**Store<State: Codable>** - Generic observable store:
+
+- `init(_ initialState, key:)` - Create store, register with C++, push initial state
+- `set(_:)` - Update state with closure
+- `set(_:to:)` - Update via keypath
+- `get(_:)` - Get property via keypath
+- Observes `BrownieStoreUpdated` notification, rebuilds typed state from C++ snapshot
+- `deinit` removes notification observer
+
+**StoreManager** - Swift-side registry (delegates to C++):
+
+- `register(store:key:)` - Register Swift store
+- `store(key:as:)` - Retrieve typed store
+- `snapshot(key:)` - Get snapshot via C++ bridge
+
+**@UseStore** - SwiftUI property wrapper:
+
+- Uses `BrownieStoreProtocol` to automatically derive store key via `storeName`
+- `wrappedValue` - Access to full `Store<State>`
+
+## JS API
+
+### React Hook
+
+```ts
+// useState-like API for store access
+const [state, setState] = useBrownieStore('BrownfieldStore');
+
+// Read state
+console.log(state.counter);
+
+// Update state (partial update)
+setState({ counter: state.counter + 1 });
+
+// Update with callback (like useState)
+setState((prev) => ({ counter: prev.counter + 1 }));
+```
+
+### Core Functions
+
+```ts
+// Subscribe to store changes
+subscribe(key: string, listener: () => void): () => void
+
+// Get current snapshot
+getSnapshot<K extends keyof BrownieStores>(key: K): BrownieStores[K]
+
+// Set state (supports partial or callback)
+type SetStateAction<T> = Partial<T> | ((prev: T) => Partial<T>)
+setState<K extends keyof BrownieStores>(key: K, action: SetStateAction<BrownieStores[K]>): void
+```
+
+### Store Cache
+
+Internal `Map<string, StoreCache>` holds:
+
+- Host object reference
+- Current snapshot
+- Registered listeners
+
+Snapshots refresh on native store change callback.
+
+## Data Transfer & Memory Model
+
+### Overview
+
+Data flows through multiple layers with **full copies** at each boundary crossing. There is no shared memory or zero-copy optimization - each layer maintains its own representation.
+
+```
+┌─────────────┐    copy    ┌─────────────┐    copy    ┌─────────────┐
+│  JS Object  │ ─────────▶ │   folly::   │ ─────────▶ │ NSDictionary│
+│  (jsi)      │ ◀───────── │   dynamic   │ ◀───────── │   / Swift   │
+└─────────────┘    copy    └─────────────┘    copy    └─────────────┘
+```
+
+Note: In the future we may explore optimizations like shared memory or zero-copy techniques, but for now simplicity and correctness are prioritized.
+
+### C++ Layer (Source of Truth)
+
+**Writes use move semantics where possible:**
+
+- `BrownieStore::set(key, value)` - value is moved into state: `state_[key] = std::move(value)`
+- `BrownieStore::setState(state)` - entire state is moved: `state_ = std::move(state)`
+- `BrownieStoreManager::registerStore(key, store)` - shared_ptr is moved into map
+
+**Reads always copy:**
+
+- `BrownieStore::get(key)` - returns copy of `folly::dynamic` value
+- `BrownieStore::getSnapshot()` - returns copy of entire state
+
+### JSI Boundary (JS ↔ C++)
+
+**JS → C++ (writes):**
+
+1. `jsi::dynamicFromValue(rt, value)` creates new `folly::dynamic` from JS value
+2. Value is then moved into C++ store
+
+**C++ → JS (reads):**
+
+1. `folly::dynamic` is copied from store
+2. `jsi::valueFromDynamic(rt, dynamic)` creates new JS value
+
+### ObjC++ Bridge (C++ ↔ Swift)
+
+**Swift → C++ (writes):**
+
+1. Swift encodes `Codable` state to JSON via `JSONEncoder`
+2. JSON deserialized to `NSDictionary`
+3. `convertIdToFollyDynamic(dict)` creates `folly::dynamic` copy
+4. Value moved into C++ store
+
+**C++ → Swift (reads):**
+
+1. `folly::dynamic` copied from store via `getSnapshot()`
+2. `convertFollyDynamicToId(dynamic)` creates `NSDictionary` copy
+3. `JSONSerialization.data(withJSONObject:)` serializes to JSON
+4. `JSONDecoder` deserializes to typed Swift struct (another copy)
+
+### Performance Implications
+
+| Operation                | Copies | Notes                             |
+| ------------------------ | ------ | --------------------------------- |
+| JS read single property  | 2      | dynamic copy + JSI conversion     |
+| JS read snapshot (unbox) | 2      | dynamic copy + JSI conversion     |
+| JS write single property | 2      | JSI→dynamic + move into store     |
+| Swift read snapshot      | 4      | dynamic→NSDictionary→JSON→Codable |
+| Swift write full state   | 4      | Codable→JSON→NSDictionary→dynamic |
+
+### Thread Safety
+
+- C++ store protected by `std::mutex` on all operations
+- Swift `StoreManager` uses `NSLock` for registry access
+- Change notifications dispatched to main queue via `dispatch_async`
+
+### Future Optimization Opportunities
+
+The ObjC++ bridge layer has the most room for optimization:
+
+- **Skip JSON serialization** - Instead of `folly::dynamic → NSDictionary → JSON → Codable`, expose individual property accessors from C++ directly to Swift. Eliminates 2 intermediate copies.
+- **Single-property sync** - Currently `pushStateToCxx()` serializes entire state. Could track dirty properties and only sync changed values.
+- **Lazy Swift state rebuild** - Defer `Codable` struct reconstruction until property actually accessed.
+- **Direct C++ ↔ Swift interop** - Swift 5.9+ has experimental C++ interop that could bypass ObjC++ bridge entirely.
