 Since the source `Dockerfile` is actually within this tutorial's own git repo, we will use this tutorial repo as the input resource called `resource-tutorial`. In the job `job-publish` build plan we `get` it first; and it is used by the `hello-world-docker-image` docker-image resource next.
 
-This means the `docker` subfolder in this tutorial section will be available at folder `resource-tutorial/51_dummy_resource_docker_image/docker` during the build plan (`resource-tutorial` is the name of the resource within the job build plan; and `51_dummy_resource_docker_image/docker` is the subfolder where the `Dockerfile` is located).

 Running the pipeline
 --------------------
 
 Your `credentials.yml` now needs your Docker Hub account credentials (see `credentials.example.yml`\):
 
 ```yaml
-meta:
-  docker:
-    email: EMAIL
-    username: USERNAME
-    password: PASSWORD
+docker-hub-email: EMAIL
+docker-hub-username: USERNAME
+docker-hub-password: PASSWORD
+docker-hub-image-hello-world: USERNAME/hello-world
 ```
 
 The `run.sh` will create the pipeline.yml and upload it to Concourse,
