 In this document we'll run through a simple example which should demonstrate the concept of the ZeroTier SDK. For this tutorial you'll need two devices (or at least the ability to run a VM or something like [Docker](https://www.docker.com/)). We will demonstrate a simple TCP server application intercepted on linux. This is only one of *many* ways the SDK can be used, but it'll at least convey the core concept how how the intercept works.

The `tcpclient4` sample app running on the device with a normal instance of ZeroTier running will be able to connect directly to your intercepted `tcpserver4` app on the second machine running the SDK.
