+Give it a `loadChildren` property instead of a `children` property.
+The `loadChildren` property takes a function that returns a promise using the browser's built-in syntax for lazy loading code using dynamic imports `import('...')`.
+The path is the location of the `AdminModule` (relative to the app root).
+After the code is requested and loaded, the `Promise` resolves an object that contains the `NgModule`, in this case the `AdminModule`.
