# Docker Installation The easiest way of installing Docker is by downloading [Docker Desktop](https://www.docker.com/products/docker-desktop/). Docker Desktop is a nice GUI front-end for Docker, so you can see your containers, images, active builds, login to your Docker Hub account, etc. It also comes with the Docker command line tools that you'll need for building Docker images. Download Docker Desktop for your computer and follow the instructions to install it. On Mac, you can access the Docker command line tools by calling `docker` from Terminal. On Windows, the Docker command line tools will be invoked by calling `docker.exe` from the Command Prompt. For brevity's sake, the rest of this material will refer to the Docker command line tools by calling `docker`. If you're following along on Windows, make sure to replace `docker` with `docker.exe`. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
