+# IDKit (Kotlin)
+
+<!-- [![Kotlin Version](https://img.shields.io/endpoint?url=https%3A%2F%2Fswiftpackageindex.com%2Fapi%2Fpackages%2Fm1guelpf%2Fziggy-vapor%2Fbadge%3Ftype%3Dswift-versions&color=brightgreen)](http://swift.org)
+[![docs](https://img.shields.io/badge/docs-latest-blue.svg)](https://swiftpackageindex.com/worldcoin/idkit-swift/documentation) -->
+
+The `IDKit` library provides a simple Kotlin interface for prompting users for World ID proofs. For our Web and React Native SDKs, check out the [IDKit JS library](https://github.com/worldcoin/idkit-js).
+
+## Usage
+
+```kotlin
+package com.worldcoin.idkit_kotlin
+class IDKitTest {
+
+    val session = Session.create(
+                appID = AppID("app_ce4cb73cb75fc3b73b71ffb4de178410"),
+                action = "test-action"
+            )
+
+    // Generate the connect URL (you would typically display this as a QR code)
+    val connectUrl = session.connectUrl
+    println("Scan this URL with the World App: $connectUrl")
+
+    // Monitor the session status
+    session.status().collect { status ->
+        when (status) {
+            is Status.WaitingForConnection -> {
+                println("Waiting for the user to scan the QR Code")
+            }
+            is Status.AwaitingConfirmation -> {
+                println("Awaiting user confirmation")
+            }
+            is Status.Confirmed -> {
+                println("Got proof: ${status.proof}")
+            }
+            is Status.Failed -> {
+                println("Got error: ${status.error.message}")
+            }
+        }
+    }
+}
+```

+
+World ID is the privacy-first identity protocol that brings global proof of personhood to the internet. More on World ID in the [announcement blog post](https://worldcoin.org/blog/announcements/introducing-world-id-and-sdk).
+
+World ID lets you seamlessly integrate authentication into your app that verifies accounts belong to real persons through [Sign in with Worldcoin](https://docs.worldcoin.org/id/sign-in). For additional flexibility and cases where you need extreme privacy, [Anonymous Actions](https://docs.worldcoin.org/id/anonymous-actions) lets you verify users in a way that cannot be tracked across verifications.
+
+Follow the [Quick Start](https://docs.worldcoin.org/quick-start) guide for the easiest way to get started.
+
+## 📄 Documentation
+
+All the technical docs for the Wordcoin SDK, World ID Protocol, examples, guides can be found at https://docs.worldcoin.org/
