+Examples:
+
+Provided that you are in a lono project and have a `my-stack` lono template definition.  To update a stack you can simply run:
+
+$ lono-cfn update my-stack
+
+The above command will generate and use the template in output/my-stack.json and parameters in params/my-stack.txt.  The template defaults by convention to the name of the stack.  The params defaults by convention to the name of the template in turn.  The convention allows the command to be a very nice short command that can be easily remembered.  Both conventions can be overridden.
+
+Here are examples of overriding the template and params name conventions.
+
+$ lono-cfn update my-stack --template different-name1
+
+The template that will be use is output/different-name1.json and the parameters will use params/different-name1.json.
+
+$ lono-cfn update my-stack --params different-name2
+
+The template that will be use is output/different-name2.json and the parameters will use params/different-name2.json.
+
+$ lono-cfn update my-stack --template different-name3 --params different-name4
+
+The template that will be use is output/different-name3.json and the parameters will use params/different-name4.json.
