When you create a group space, you are able to select the template. If those templates do not fit your needs, you can always create your own templates.
Suppose each division in your company can have their own space, but they all need to have the same structure and services. This is an ideal situation to create a space template. When you create a new space for a division, you just need to select the division template and that's it. This way you don't need to create all the pages over and over again.
A template is always created based upon an existing group space, so you first need to create a space that will be the source for your template.
For this recipe, you need a WebCenter Space environment.
