# Installing Docker — Docker

> Get Docker Desktop or Engine on your machine and confirm it works.

## Desktop vs Engine

**Docker Desktop** (Windows/macOS) bundles a GUI, a Linux VM, and the CLI. On Linux, you typically install just the **Docker Engine** — the daemon and CLI, no extra VM needed.

## Verify the install

After installing, confirm the CLI is on your PATH and the daemon is running.

```bash
docker --version
# Docker version 27.x.x, build xxxxxxx

docker info   # shows daemon status, containers, images, etc.
```

## Run hello-world

The classic smoke test — it pulls a tiny image and runs it, printing a confirmation message.

```bash
docker run hello-world
```

Output:

```
Hello from Docker!
This message shows that your installation appears to be working correctly.
```
