}
```

Add dependency

```kotlin
kotlin {
    linuxX64()
    // Add other platforms

    sourceSets {
        commonMain.dependencies {
            implementation("cn.rtast.nmdns:native-mdns:0.0.2")

There is a simple airplay2 service

```kotlin
val service = registerService(
    serviceType = "_airplay._tcp.local.",
    serviceName = "AP@RTAST",
    hostname = "rtakland.local.",
    ipAddress = "192.168.10.104",
    port = 7001,
    bindAddress = "192.168.10.104",
    mdnsPort = 5356,
)
while (true) {
    service.broadcast()
    delay(2000L) // or use cn.rtast.nmdns.sleep1(2) sleep 2 seconds
}
```
