+## Label types
+
+Label entries require "type" and "name". All labels can include
+a "title" field, which is added as a hover-on text, and "default" for
+the default value.
+
+In some cases more fields required.
+
+- checkbox: If "default": "on", checkbox is selected. Otherwise it is unselected.
+- text: Any string, if no default: ""
+- number: Any number entry, if no default: ""
+- range: Requires  "min" and "max" values. if no default, default = min.
+- select: Requires a list of "options".
+- info: Not a selection. Add "title" field to show text instead.
