 For the following explanations, we will use the first few lines of the `download.yml` playbook as an example:
 ```
-- include: tasks/setup.yml group=hdfs-namenode:hdfs-datanode:download

 * `all_instances` - All hosts from all groups that are either being provisioned and/or used are lumped together into a single host group.
 The purpose of this group is so we can write out the hostname and ips of every server to the `/etc/hosts` file of every server. This way, 
 every server, knows about every other server.
 
 * We do some parsing of host names to generate groups of related servers based on the the way they are named. For example,
-in the `hdfs-datanode` group we have the hostnames `dcc-hadoop-worker-[1:2]`. A group called `hadoop_worker` is created containing 
+in the `hadoop-worker` group we have the hostnames `dcc-hadoop-worker-[1:2]`. A group called `hadoop_worker` is created containing 
 the hosts `dcc-hadoop-worker-1` and `dcc-hadoop-worker-2`. The utility of this becomes more obvious when you look at groups and playbooks that use
 a wider array of servers with different purposes, such as the `portal.yml` playbook with the `portal` host group.
