Using smart objects are a common way to bundle something together while at the same time keep the integrity of the original image or text quality. 


To edit a smart object:

1. Select the layer on the layers pallet 
2. Double click on the smart object icon and it will open the smart object in a new window. 
3. Make your changes and then close the window for the smart object.  This will prompt a message asking you to save the object.  Say "yes"
4. The smart object will then update in the original template to your adjustments you made.
