when creating a kotlin multiplatform project like ...

# gradle

[Torbilicious]

when creating a kotlin multiplatform project like in the official documentation

plugins {
    id 'org.jetbrains.kotlin.multiplatform' version '1.3.10'
}

repositories {
    mavenCentral()
}

kotlin {
    targets {
        fromPreset(presets.jvm, 'jvm')
        fromPreset(presets.js, 'js')
        fromPreset(presets.mingwX64, 'mingw')
    }
    
    sourceSets { /* ... */ }
}

how do you go about adding the

kotlin { }

block in the kotlin gradle dsl?
