+# combine
+
+`combine` middleware lets you create a new state by combining an initial state with additional
+state created by a function. This middleware is particularly useful due to infers the state, so you
+don't need to type it.
+
+```js
+combine(initialState, additionalStateCreator)
+```
+
+- [Reference](#reference)
+  - [Signature](#combine-signature)
+  - [`setState` function](#setstate-function)
+  - [`getState` function](#getstate-function)
+  - [`subscribe` function](#subscribe-function)
+  - [`storeApi`](#storeapi)
+- [Usage](#usage)
+- [Troubleshooting](#troubleshooting)
+
+## Reference
+
+### `combine` Signature
+
+```ts
+combine<T, U>(initialState: T, additionalStateCreatorFn: StateCreator<T, [], [], U>): StateCreator<Omit<T, keyof U> & U, [], []>
+```
+
+#### Parameters
+
+- `initialState`: The value you want the state to be initially. It can be a value of any type,
+  except a function.
+- `additionalStateCreatorFn`: The state creator function that specifies how the state gets
+  initialized and updated. It must be pure, should take `setState` function, `getState` function
+  and `storeApi` as arguments.
+
+#### Returns
+
+`combine` returns a state creator function.
+
+### `setState` function
+
+The `setState` function lets you update the state to a different value and trigger re-render. You
+can pass the next state directly, a next partial state, a function that calculates it from the
+previous state, or replace it completely.
+
+#### Parameters
+
+- `nextState`: The value that you want the state to be. It can be a value of any type, but there is
+  a special behavior for functions.
+  - If you pass an object as a `nextState`. It will shallow merge `nextState` with the current
+    state. You can pass only the properties you want to update, this allows for selective state
+    updates without modifying other properties.
+  - If you pass a non-object as a `nextState`, make sure you use `replace` as `true` to avoid
+    unexpected behaviors.
+  - If you pass a function as a `nextState`. It must be pure, should take current state as its
+    only argument, and should return the next state. The next state returned by the updater
+    function face the same restrictions of any next state.
+- `replace`: This optional boolean flag controls whether to replace the entire state or merge the
+  update with the current state.
+
+#### Returns
+
+`setState` function do not have a return value.
+
+### `getState` function
+
+The `getState` function lets you access to the current state. It can be stale on asynchronous
+operations.
+
+### `subscribe` function
+
+The `subscribe` function lets you subscribe to state updates. It should take current state and
+previous state as arguments.
+
+#### Parameters
+
+- `currentState`: The current state.
+- `previousState`: The previous state.
+
+#### Returns
+
+`subscribe` returns a function that lets you unsubscribe.
+
+### `storeApi`
+
+The `storeApi` lets you access to the store API functions like
+[`setState` function](#setstate-function), [`getState` function](#getstate-function), and
+[`subscribe` function](#subscribe-function).

+## Store
+
+The Store lets you access to the store API utilities.
+
+## API Utilities
+
+These store API utilities are: `setState` function, `getState` function, and `subscribe` function.
+
+### `setState` function
+
+The `setState` function lets you update the state to a different value and trigger re-render. You
+can pass the next state directly, a next partial state, a function that calculates it from the
+previous state, or replace it completely.
+
+#### Parameters
+
+- `nextState`: The value that you want the state to be. It can be a value of any type, but there is
+  a special behavior for functions.
+  - If you pass an object as a `nextState`. It will shallow merge `nextState` with the current
+    state. You can pass only the properties you want to update, this allows for selective state
+    updates without modifying other properties.
+  - If you pass a non-object as a `nextState`, make sure you use `replace` as `true` to avoid
+    unexpected behaviors.
+  - If you pass a function as a `nextState`. It must be pure, should take current state as its
+    only argument, and should return the next state. The next state returned by the updater
+    function face the same restrictions of any next state.
+- `replace`: This optional boolean flag controls whether the state is completely replaced or only
+  shallow updated, through a shallow merge.
+
+#### Returns
+
+`setState` function do not have a return value.
+
+### `getState` function
+
+The `getState` function lets you access to the current state. It can be stale on asynchronous
+operations.
+
+### `subscribe` function
+
+The `subscribe` function lets you subscribe to state updates. It should take current state, and
+its previous state as arguments.
+
+#### Parameters
+
+- `currentState`: The current state.
+- `previousState`: The previous state.
+
+#### Returns
+
+`subscribe` returns a function that lets you unsubscribe from itself.

+create<T>()(stateCreatorFn: StateCreator<T, [], []>): UseBoundStore<StoreApi<T>>
+```
+
+#### Parameters
+
+- `stateCreatorFn`: The value you want the state to be initially. It can be a value of any type,
+  but when you pass a function should take `setState` function, `getState` function and `storeApi`
+  as arguments.
+
+#### Returns
+
+`create` returns a React Hook with Store API attached:
+
+1. The React Hook that lets you return data that is based on current state, using a
+   [`selector` function](#selector-function). It should take a selector function as its only
+   argument.
+
+### `selector` function
+
+The `selector` function lets you return data that is based on current state. It should take current
+state as its only argument.
+
+### `setState` function
+
+The `setState` function lets you update the state to a different value and trigger re-render. You
+can pass the next state directly, a next partial state, a function that calculates it from the
+previous state, or replace it completely.
+
+#### Parameters
+
+- `nextState`: The value that you want the state to be. It can be a value of any type, but there is
+  a special behavior for functions.
+  - If you pass an object as a `nextState`. It will shallow merge `nextState` with the current
+    state. You can pass only the properties you want to update, this allows for selective state
+    updates without modifying other properties.
+  - If you pass a non-object as a `nextState`, make sure you use `replace` as `true` to avoid
+    unexpected behaviors.
+  - If you pass a function as a `nextState`. It must be pure, should take current state as its
+    only argument, and should return the next state. The next state returned by the updater
+    function face the same restrictions of any next state.
+- `replace`: This optional boolean flag controls whether the state is completely replaced or only
+  shallow updated, through a shallow merge.
+
+#### Returns
+
+`setState` function do not have a return value.
+
+### `getState` function
+
+The `getState` function lets you access to the current state. It can be stale on asynchronous
+operations.
+
+### `subscribe` function
+
+The `subscribe` function lets you subscribe to state updates. It should take current state, and
+its previous state as arguments.
+
+#### Parameters
+
+- `currentState`: The current state.
+- `previousState`: The previous state.
+
+#### Returns
+
+`subscribe` returns a function that lets you unsubscribe from itself.
+
+### `storeApi`
+
+The `storeApi` lets you access to the store API utilities. These store API utilities are:
+[`setState` function](#setstate-function), [`getState` function](#getstate-function), and
+[`subscribe` function](#subscribe-function).
+
+## Usage
+
+### Updating state base on previous state

+its previous state as arguments.
+
+#### Parameters
+
+- `currentState`: The current state.
+- `previousState`: The previous state.
+
+#### Returns
+
+`subscribe` returns a function that lets you unsubscribe from itself.

+
+```js
+useStore(api, selector)
+```

+  - [Signature](#usestore-signature)
+  - [`selector` function](#selector-function)
+  - [`setState` function](#setstate-function)
+  - [`getState` function](#getstate-function)

+
+## Reference
+
+### `useStore` Signature
+
+```ts
+useStore<StoreApi<T>, U = T>(storeApi: StoreApi<T>, selectorFn?: (state: T) => U) => UseBoundStore<StoreApi<T>>
+```
+
+#### Parameters
+
+- `storeApi`: The instance that lets you access to store API utilities.
+- `selectorFn`: A function that lets you return data that is based on current state.
+
+#### Returns
+
+`useStore` returns current state or returns any data based on current state depending on the
+selector function.
+
+### `selector` function
+
+The `selector` function lets you return data that is based on current state. It should take current
+state as its only argument.
+
+### `setState` function
+
+The `setState` function lets you update the state to a different value and trigger re-render. You
+can pass the next state directly, a next partial state, a function that calculates it from the
+previous state, or replace it completely.
+
+#### Parameters
+
+- `nextState`: The value that you want the state to be. It can be a value of any type, but there is
+  a special behavior for functions.
+  - if you pass an object as a `nextState`. It will shallow merge `nextState` with the current
+    state. You can pass only the properties you want to update, this allows for selective state
+    updates without modifying other properties.
+  - if you pass a non-object as a `nextState`, make sure you use `replace` as `true` to avoid
+    unexpected behaviors.
+  - if you pass a function as a `nextState`. It must be pure, should take current state as its
+    only argument, and should return the next state. The next state returned by the updater
+    function face the same restrictions of any next state.
+- `replace`: This optional boolean flag controls whether to replace the entire state or merge the
+  update with the current state.
+
+#### Returns
+
+`setState` function do not have a return value.
+
+### `getState` function
+
+The `getState` function lets you access to the current state. It can be stale on asynchronous
+operations.
+
+### `subscribe` function
+
+The `subscribe` function lets you subscribe to state updates. It should take current state and
+previous state as arguments.
+
+#### Parameters
+
+- `currentState`: The current state.
+- `previousState`: The previous state.
+
+#### Returns
+
+`subscribe` returns a function that lets you unsubscribe.
+
+### `storeApi`
+
+The `storeApi` lets you access to the store API utilities like
+[`setState` function](#setstate-function), [`getState` function](#getstate-function),
+and [`subscribe` function](#subscribe-function).
