# Initialization

After installing the Wepin Compose Multiplatform Login Library, the next step is to initialize the SDK. SDK initialization involves creating an instance of `WepinLogin` and using the `init()` function to proceed.

## Import SDK

To use the Wepin Compose Multiplatform Login Library, you first need to import the SDK. Add the following import statements:

```kotlin
import com.wepin.cm.loginlib.WepinLogin
import com.wepin.cm.loginlib.types.*
```

## **Creating and Initializing the `WepinLogin` Instance**

Before creating an instance of `WepinLogin`, you must register your app's Android/iOS information in the Wepin Workspace.

{% content-ref url="/pages/cfg4nwJBI8VfiJpH4EW8" %}
[Workspace](/en/wepin/workspace.md)
{% endcontent-ref %}

Using the registered app information, create an instance of `WepinLogin`.

```kotlin
private val wepinLogin: WepinLogin = WepinLogin(
    WepinLoginOptions(
        context = context,    //Android: Context, ios: UIViewController
        appId = appId,
        appKey = appKey
    )
)
wepinLogin.init()
```

## **Checking Initialization Status (isInitialized)**

You can check whether the `WepinLogin` instance has been successfully initialized by using the `isInitialized` method.  

The return value is as follows:

* **\<Boolean>**\
  Returns `true` if initialization was successful, and `false` if it failed.

```dart
if(wepinLogin.isInitialized()) {
    // Success to initialize WepinLogin
}
```
