 Now use Azure Container Registry to build and push an image. First, create a local working directory and then create a Dockerfile named *Dockerfile* with the single line: `FROM mcr.microsoft.com/hello-world`. This is a simple example to build a Linux container image from the `hello-world` image hosted at Microsoft Container Registry. You can create your own standard Dockerfile and build images for other platforms. If you are working at a bash shell, create the Dockerfile with the following command:
 
 ```bash
-echo FROM mcr.microsoft.com/hello-world > Dockerfile
+echo "FROM mcr.microsoft.com/hello-world" > Dockerfile
 ```
 
 Run the [az acr build][az-acr-build] command, which builds the image and, after the image is successfully built, pushes it to your registry. The following example builds and pushes the `sample/hello-world:v1` image. The `.` at the end of the command sets the location of the Dockerfile, in this case the current directory.
