+```
+
+### Making a transition for todo, in_progres and done

+
+### Using AIssue Interface and Trait with Eloquent Models
+To turn an Eloquent Model into an AIssue ; 
+Model must implement AIssueModelContract and use AIssueModelTrait Trait.
+After adding AIssueModelContract trait, you will be able to use AIssue methods within the model
+```php
+
+    namespace App\Models\ExampleModel;
+
+    use AuroraWebSoftware\AIssue\Contracts\AIssueModelContract;
+    use AuroraWebSoftware\AIssue\Traits\AIssueModelTrait;
