This document provides instructions for setting up Optimus Cloud, which connects devices together for appium testing. It involves 3 main steps: 1. Deploying the Optimus Cloud services using Docker Compose on a machine like a MacMini. 2. Deploying the Optimus Worker service on multiple machines where devices/emulators will run using the optimus-runner gem. 3. Updating test clients with the appropriate Optimus Cloud language binding like Java, and running tests to validate the cloud setup.
