# OE Learning Trails

Emporix Orchestration Engine provides Hello World exercises designed to acquaint you with the realm of value streams and the OE environment. As a brief overview of OE , we can construct a value stream from the ground up, allowing you to grasp the concepts and familiarize yourself with the available tools.

Before starting with the trails, take a look at some basic information about how the processes in OE are built - see [Value Stream Components](/oe/value-streams/working-with-value-streams/value-streams-components.md) guide.

Then, go through the trails in the following order:

1. [Setting up a First Value Stream](/oe/getting-started/trail/setting-up-a-first-value-stream.md)
2. [Adding a Conditional Step in a Value Stream](/oe/getting-started/trail/adding-conditional-step-in-value-stream.md)
