+### Defining custom ETags
+The static method `EtagConditionals::etagGenerateUsing()` allows you to have full control over how your Etag is generated by passing a callback as argument. 
+This means you can do simple things like returning an ETag using a different algorithm, or other custom solutions. 
+```php
+        EtagConditionals::etagGenerateUsing(function (\Symfony\Component\HttpFoundation\Response $response) {
+            return hash('sha256', $response->getContent());
+        });
+```
+```php
+        EtagConditionals::etagGenerateUsing(function (\Illuminate\Http\Request $request, \Symfony\Component\HttpFoundation\Response $response) {
+            return Cache::rememberForever('etag.'.$request->url(), function () use ($response) {
+                 return md5($response->getContent());
+            });
+        });
+```
