+# Annotation Project Group Creation
+Annotation projects often involve more than one annotator.
+
+Project Group instances allow the creation and management of a group of annotation projects from one screen.
+
+## Annotation Project Group Creation
+
+Creating a Project Group is similar to regular [Annotation Project Creation](project_admin.md), but differs in a few 
+key ways. 
+
+They can be used to group existing projects together, or to create a set of Annotation Projects.
+
+## Key Differences from Regular Project Creation
+
+When completing a Project Group form, **Create Associated Projects** is a key parameter:
+
+### Create Associated Projects: True
+If checked will create an Annotation Project for each Annotator selected in the list. All selected Admins will be included as 'annotators' on each Project created. This saves 
+the current steps of creating a 'template' projec then cloning, renaming and re-permissioning each project which happens with
+regular project creation for multiple annotators. Each Project will be called **<Project Group Name> - <Annotator Name>**.
+
+
+### Create Associated Projects: False
+If False the only important parameters will be ProjectGroup Name and description. All other parameters will be ignored. The expectation here is 
+that the projects that are to be grouped already exist, and each Project will be added to the new Project Group manually.
+
+## Best Practise
+Project Groups provide a convenience method for the creating managing grorups of Annotation Projects. Changes such as CUI filters, and projec settings changed once
+in the group will flow down into the associated Annotation Projects.
+
+
+
+## Using Annotation Project Groups
+Regular, non-admin Users of MedCATTrainer, i.e. regular annotators, will not see the option to view Project Groups. 
+
+Admin users will see an action bar as shown:
+![Project Groups Available](_static/img/project-groups-view-available.png)
+
+Selecting this view will show all available Project Groups to the logged in user.
+![Project Groups view](_static/img/project-groups-view.png)
+
+Selecting a group now opens a lightbox with the list of projects in this group:
+![Project Group Contents](_static/img/projects-in-group.png)
+
+
+## Other Benefits of Project Groups
+
+Further enhancements will allow metric further comparisson between projects in a group, gamification, standard annotation metric reporting (e.g. IIA / Cohen's Kappa statistics etc.)
