Can anyone run me through the "Get started" Tutorial for unreal?

Hey,

Can somone help run me through this link

I Need to add this code.

Summary

pluginManagement {
repositories {
google()
mavenCentral()
gradlePluginPortal()
}
}

dependencyResolutionManagement {
repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
repositories {
google()
mavenCentral()
}
}

rootProject.name = “My Application”
include(“:app”)

Into my build.gradle.

Which assumably is this one?

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        google()
        mavenCentral()
//        jcenter()
    }
    dependencies {
        classpath project.hasProperty('ANDROID_TOOLS_BUILD_GRADLE_VERSION') ? project.property('ANDROID_TOOLS_BUILD_GRADLE_VERSION') : 'com.android.tools.build:gradle:8.9'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
    apply from: 'buildscriptAdditions.gradle', to: buildscript
}

apply from: 'baseBuildAdditions.gradle'

allprojects {
    repositories {
        google()
        mavenCentral()
//        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

I’ve read somewhere We aren’t meant to modify build.gradles. We are meant to use upl files for unreal?
