 php artisan ziggy:generate --types
 ```
 
+To make your IDE aware that Ziggy's `route()` helper is available globally, and to type it correctly, add a declaration like this in a `.d.ts` file somewhere in your project:
+
+```ts
+import routeFn from 'ziggy-js';
+
+declare global {
+    var route: typeof routeFn;
+}
+```
+
+If you don't have Ziggy's NPM package installed, add the following to your `jsconfig.json` or `tsconfig.json` to load Ziggy's types from the Composer vendor directory:
+
+```json
+{
+    "compilerOptions": {
+        "paths": {
+            "ziggy-js": ["./vendor/tightenco/ziggy"]
+        }
+    }
+}
+```
