## Project setup

To add the Navigation 3 library to your existing project, add the following to your`libs.versions.toml`:  

    [versions]
    nav3Core = "1.0.0"
    lifecycleViewmodelNav3 = "2.10.0"
    kotlinSerialization = "2.1.21"
    kotlinxSerializationCore = "1.8.1"
    material3AdaptiveNav3 = "1.3.0-alpha04"

    [libraries]
    # Core Navigation 3 libraries
    androidx-navigation3-runtime = { module = "androidx.navigation3:navigation3-runtime", version.ref = "nav3Core" }
    androidx-navigation3-ui = { module = "androidx.navigation3:navigation3-ui", version.ref = "nav3Core" }

    # Optional add-on libraries
    androidx-lifecycle-viewmodel-navigation3 = { module = "androidx.lifecycle:lifecycle-viewmodel-navigation3", version.ref = "lifecycleViewmodelNav3" }
    kotlinx-serialization-core = { module = "org.jetbrains.kotlinx:kotlinx-serialization-core", version.ref = "kotlinxSerializationCore" }

    androidx-material3-adaptive-navigation3 = { group = "androidx.compose.material3.adaptive", name = "adaptive-navigation3", version.ref = "material3AdaptiveNav3" }

    [plugins]
    # Optional plugins
    jetbrains-kotlin-serialization = { id = "org.jetbrains.kotlin.plugin.serialization", version.ref = "kotlinSerialization"}

Also, update your compile SDK to 36 or above:  

    [versions]
    compileSdk = "36"

Add the following to your**app** build file`app/build.gradle.kts`:  

    plugins {
        ...
        // Optional, provides the @Serialize annotation for autogeneration of Serializers.
        alias(libs.plugins.jetbrains.kotlin.serialization)
    }

    dependencies {
        ...
        implementation(libs.androidx.navigation3.ui)
        implementation(libs.androidx.navigation3.runtime)
        implementation(libs.androidx.lifecycle.viewmodel.navigation3)
        implementation(libs.androidx.material3.adaptive.navigation3)
        implementation(libs.kotlinx.serialization.core)
    }
