Within 30 minutes, you should be able to run the Hello World example and learn how it is constructed.

 Fortunately — unlike with prose — established best practices can guide us through these initial steps. In the remainder of this guide, we examine the core logic of a simple Pekko application to introduce you to actors and show you how to formulate solutions with them. The example demonstrates common patterns that will help you kickstart your Pekko projects.
 
 ## Prerequisites

 As illustrated below, all actors have a common parent, the user guardian, which is defined and created when you start the @apidoc[actor.typed.ActorSystem].
-As we covered in the @scala[[Quickstart Guide](https://developer.lightbend.com/guides/akka-quickstart-scala/)]@java[[Quickstart Guide](https://developer.lightbend.com/guides/akka-quickstart-java/)], creation of an actor returns a reference that is a valid URL.
