laravel - ロケールの ResetPassword 通知で Lang::get('Reset Password Notification') を翻訳する方法は?

Question

通知メッセージのテキストを翻訳するには? /vendor/laravel/framework/src/Illuminate/Auth/Notifications/ResetPassword.php' copied it's content to app/Notifications/PasswordReset.php`というパスが見つかりました

protected function buildMailMessage($url)
{
    return (new MailMessage)
        ->subject(Lang::get('Reset Password Notification'))
        ->line(Lang::get('You are receiving this email because we received a password reset request for your account.'))
        ->action(Lang::get('Reset Password'), $url)
        ->line(Lang::get('This password reset link will expire in :count minutes.', ['count' => config('auth.passwords.'.config('auth.defaults.passwords').'.expire')]))
        ->line(Lang::get('If you did not request a password reset, no further action is required.'));
}

文字列を翻訳する方法、翻訳Lang::get('Reset Password Notification')をどこに置くか、ロケールを設定する方法は?
