 Using UUIDs in Laravel is made super simple in combination with [laravel-model-uuid](https://github.com/michaeldyrynda/laravel-model-uuid). Note that when using `laravel-model-uuid`, if you are not casting your UUIDs or calling the query builder directly, you'll need to use the `getBytes` method when setting the UUID on the database, otherwise your values will be truncated. Depending on your MySQL/MariaDB configuration, this may lead to application errors due to strict settings. See #1 for more information.
