-This tutorial teaches the Docker container build and deploy tasks for a .NET Core application. The [Docker platform](https://docs.docker.com/engine/docker-overview/#the-docker-platform) uses the [Docker Engine](https://docs.docker.com/engine/docker-overview/#docker-engine) to quickly build and package apps as [Docker images](https://docs.docker.com/glossary/?term=image). These images are written in the [Dockerfile](https://docs.docker.com/glossary/?term=Dockerfile) format to be deployed and run in a [layered container](https://docs.docker.com/engine/userguide/storagedriver/imagesandcontainers/#container-and-layers).
+This tutorial teaches you how to build a Docker image that contains your .NET Core application. The image can be used to create containers for your local development environment, private cloud, or public cloud.
