What should I put in compost bins?

What should I put in compost bins?
Anything organic, i.e. anything that was once living, whether animal or vegetable, can be composted but some materials are more appropriate than others for home composting.
Organic material falls into two categories: Green and Brown
Green or  “nitrogen rich” organic material is wet and often green like grass clippings or fruit and vegetables. 
Brown or “carbon rich” organic material is dry, woody material that is usually brown, such as fallen leaves and tree-cuttings.
The following list of materials can be composted at home. It has been separated into “Green” and “Brown” for simple identification.
