-IoT Edge moves your existing business logic to devices operating at the edge. To prepare your applications and workloads to run as [IoT Edge modules](iot-edge-modules.md), you need to build them as containers. This article provides guidance around how to configure your development environment so that you can successfully create an IoT Edge solution. Once you have your development environment set up, you can learn how to [develop your own IoT Edge modules](module-development.md).

-In any IoT Edge solution, there are at least two machines to consider: the IoT Edge device (or devices) that runs the IoT Edge module, and the development machine that builds, tests, and deploys modules. This article focuses primarily on the development machine. For testing purposes, the two machines can be the same. You can run IoT Edge on your development machine and deploy modules to it.

This article focuses primarily on the development machine. For testing purposes, the two machines can be the same. You can run IoT Edge on your development machine and deploy modules to it.
 
 ## Operating system
 
 IoT Edge runs on a specific set of [supported operating systems](support.md). When developing for IoT Edge, you can use most operating systems that can run a container engine. The container engine is a requirement on the development machine to build your modules as containers and push them to a container registry.
 
 If your development machine can't run IoT Edge, skip to the [Testing tools](#testing-tools) section of this article to learn how to test and debug locally.
 
-The operating systems of the development machine and IoT Edge devices don't need to match. However, the container operating system must be consistent with the development machine and the IoT Edge device. For example, you can develop modules on a Windows machine and deploy them to a Linux device. The Windows machine needs to run Linux containers to build the modules for the Linux device.

 ## Container engine
 
 The central concept of IoT Edge is that you can remotely deploy your business and cloud logic to devices by packaging it into containers. To build containers, you need a container engine on your development machine.
 
-Any container engine compatible with the Open Container Initiative, like Docker, is capable of building IoT Edge module images. Moby is the supported container engine for IoT Edge devices in production. If you're using Ubuntu Core snaps, the Docker snap is serviced by Canonical and supported for production scenarios.

 The Azure IoT EdgeHub Dev Tool provides a local development and debug experience. The tool helps start IoT Edge modules without the IoT Edge runtime so that you can create, develop, test, run, and debug IoT Edge modules and solutions locally. You don't have to push images to a container registry and deploy them to a device for testing.
 
-The IoT EdgeHub Dev Tool was designed to work in tandem with the Visual Studio and Visual Studio Code extensions, and with the IoT Edge Dev Tool. The dev tool supports inner loop development and outer loop testing, so it integrates with other DevOps tools too.

 ## DevOps tools
 
-When you're ready to develop at-scale solutions for extensive production scenarios, take advantage of modern DevOps principles including automation, monitoring, and streamlined software engineering processes. IoT Edge has extensions to support DevOps tools including Azure DevOps, Azure DevOps Projects, and Jenkins. If you want to customize an existing pipeline or use a different DevOps tool like CircleCI or TravisCI, you can do so with the CLI features included in the IoT Edge Dev Tool.
