 // The TextWidget generator needs one environment variable, called WTF_WIDGET_NAME, which will
 // be the name of the TextWidget it generates. If the variable hasn't been set, the generator
 // will use "NewTextWidget". On Linux and macOS the command can be run as
-// 'WTF_WIDGET_NAME=MyNewWidget go generate text'.
+// 'WTF_WIDGET_NAME=MyNewWidget go generate -run=text'.
