 @name $injector:nomod
 @fullName Module Unavailable
 @description
+
+This error occurs when trying to "re-open" a module that has not yet been defined.
+
+To define a new module, call {@link api/angular.module angular.module} with a name
+and an array of dependent modules, like so:
+
+```
+// When defining a module with no module dependencies,
+// the requires array should be defined and empty.
+var myApp = angular.module('myApp', []);
+```
+
+To retrieve a reference to the same module for further configuration, call
+`angular.module` without the `requires` array.
+
+```
+var myApp = angular.module('myApp');
+```
+
+Calling `angular.module` without the `requires` array when the module has not yet
+been defined causes this error to be thrown. To fix it, define your module with
+a name and an empty array, as in the first example above.
