Adds a simple system to pre-fill fields on new content nodes based on the field values of other content nodes called "content templates".
Be sure to install Document Type Picker first: https://our.umbraco.org/projects/backoffice-extensions/document-type-picker-for-v7/
And add this app setting to your web.config to indicate the ID of the content templates root node:
<add key="ContentTemplates-RootNode" value="1234" />
