+You can also disable revisioning after X many revisions have been made by setting `$historyLimit` to the number of revisions you want to keep before stopping revisions.

+```php
+namespace MyApp\Models;
+
+class Article extends Eloquent {
+    use Venturecraft\Revisionable\RevisionableTrait;

+    protected $revisionEnabled = true;
+    protected $historyLimit = 500; //Stop tracking revisions after 500 changes have been made.
