+# Go client for the Docker Engine API
+
+The `docker` command uses this package to communicate with the daemon. It can also be used by your own Go applications to do anything the command-line interface does – running containers, pulling images, managing swarms, etc.
+
+For example, to list running containers (the equivalent of `docker ps`):
+
+```go
+package main
+
+import (
+	"context"
+	"fmt"
+
+	"github.com/docker/docker/api/types"
+	"github.com/docker/docker/client"
+)
+
+func main() {
+	cli, err := client.NewEnvClient()
+	if err != nil {
+		panic(err)
+	}
+
+	containers, err := cli.ContainerList(context.Background(), types.ContainerListOptions{})
+	if err != nil {
+		panic(err)
+	}
+
+	for _, container := range containers {
+		fmt.Printf("%s %s\n", container.ID[:10], container.Image)
+	}
+}
+```
