 When evaluating a language model, it's is not unusual to test across a number of tasks that may not be related to one another in order to assess a variety of capabilities. To this end, it may be combursome to have to list the set of tasks or add a new group name to each yaml of each individual task.
 
-To solve this, we can create a group yaml config. This is a config that contains the names of the tasks that should be included in a particular group. The config consists of two main keys `group` which denotes the name of the group and `task` which is where we can list the tasks. The tasks listed in `task` are the task names that have been registered. A good example would be the list of tasks used to evaluate the Pythia Suite.
