 The following will build the root Dockerfile, tag the image as `myorg/myrepository:latest`, log in to Docker Hub using GitHub secrets, and push the image to the Docker Hub repository `myorg/myrepository`:
 
 ```yaml

-  password: ${{ secrets.DOCKER_PASSWORD }}

 The following will build the root Dockerfile, tag the image with the git reference and SHA as described above, log in to Docker Hub using GitHub secrets, and push the image to the Docker Hub repository `myorg/myrepository`:
 
 ```yaml
-uses: docker/build-push-action@v1
-with:
-  username: ${{ secrets.DOCKER_USERNAME }}

 The following will only push the image when the event that kicked off the workflow was a push of a git tag:
 
 ```yaml
-uses: docker/build-push-action@v1
-with:
-  username: ${{ secrets.DOCKER_USERNAME }}
-  password: ${{ secrets.DOCKER_PASSWORD }}
-  repository: myorg/myrepository
-  tag_with_ref: true

 ```
 
 The following builds the `mytarget` stage and pushes that:
  
 ```yaml
-uses: docker/build-push-action@v1
-with:
-  username: ${{ secrets.DOCKER_USERNAME }}
-  password: ${{ secrets.DOCKER_PASSWORD }}
-  repository: myorg/myrepository

 The following will build the root Dockerfile, tag the image as `myorg/myrepository:latest`, log in to Google Container Registry using GitHub secrets (where `DOCKER_PASSWORD` is a [JSON key](https://cloud.google.com/container-registry/docs/advanced-authentication#json-key)), and push the image to the GCR repository `myorg/myrepository`:
  
 ```yaml
