Then in the `FilePageReader` file add this code at the end of your `readBySlug` method:

```php
$path = "$this->pageFolder/$slug.md";

if (!file_exists($path)) {
throw new InvalidPageException($slug);
foreach (new FilesystemIterator($this->pageFolder) as $page) {
if ($page === "$slug.md") {
$page = $page->openFile();
return $page->fread($page->getSize());
}
}

return file_get_contents($path);
throw new InvalidPageException($slug);
```

Now if you navigate to a page that does not exist, you should see an `InvalidPageException`. If a file exists, you should see the content.
