Create a page which gives an overview of all ways how a user / developer can create 

• JCR nodetype
• JCR workspace

With

• "old way" (not referring to content-types:0.x but referring to node-types.xml and module-descriptor.xml)
• the new way by 
  • creating content-type definition item
  • creating a node-types.xml as a Magnolia Resource

Also providing pros & cons for the different possibilities - plus links to other content (which hopefully treats the distinct sup topics on depth)
