+# Agora Token Generator Kotlin
+
+This project provides the implementation of Agora AccessToken2 in Kotlin.
+
+## Project Structure
+
+- `src/main/kotlin`: Core logic for generating tokens.
+- `src/sample/kotlin`: Sample usage of the token builders.
+- `src/test/kotlin`: Unit tests for the implementation.
+
+## How to use
+
+### Build
+
+You can build the project using Gradle:
+
+```bash
+./gradlew build
+```
+
+### Run Sample
+
+To run the sample, you need to set the following environment variables:
+- `AGORA_APP_ID`: Your Agora App ID.
+- `AGORA_APP_CERTIFICATE`: Your Agora App Certificate.
+
+Then run:
+
+```bash
+./gradlew runSample
+```
+
+(Note: You might need to add a `runSample` task to your `build.gradle.kts` if you want to run it via Gradle)
+
+### Run Tests
+
+```bash
+./gradlew test
+```
+
+## Example Usage
+
+```kotlin
+import io.agora.media.RtcTokenBuilder2
+
+val appId = "YOUR_APP_ID"
+val appCertificate = "YOUR_APP_CERTIFICATE"
+val channelName = "YOUR_CHANNEL_NAME"
+val uid = 123
+val role = RtcTokenBuilder2.Role.ROLE_PUBLISHER
+val tokenExpire = 3600
+val privilegeExpire = 3600
+
+val tokenBuilder = RtcTokenBuilder2()
+val token = tokenBuilder.buildTokenWithUid(
+    appId, appCertificate, channelName, uid, role,
+    tokenExpire, privilegeExpire
+)
+println("Token: $token")
+```
