 This is a framework agnostic cron jobs scheduler that can be easily integrated with your project or run as a standalone command scheduler.
-The idea was originally inspired by the [Laravel Task Scheduling](http://laravel.com/docs/5.1/scheduling).
-
-## Installing via Composer
-The recommended way is to install the php-cron-scheduler is through [Composer](https://getcomposer.org/).
-Please refer to [Getting Started](https://getcomposer.org/doc/00-intro.md) on how to download and install Composer.
-
-After you have downloaded/installed Composer, run
-
-`php composer.phar require peppeocchi/php-cron-scheduler`
-
-or add the package to your `composer.json`
-```json
-{
-    "require": {
-        "peppeocchi/php-cron-scheduler": "3.*"
-    }
-}
-```
+Split from peppeocchi/php-cron-scheduler
 
-Scheduler V3 requires php >= 7.1, please use the [v2 branch](https://github.com/peppeocchi/php-cron-scheduler/tree/v2.x) for php versions < 7.1.
+Scheduler requires php >= 7.4

 You can define one or multiple email addresses where you want the output of your script/command/function execution to be sent to.
 In order for the email to be sent, the output of the job needs to be sent first to a file.
 In fact, the files will be attached to your email address.

-You can optionally customize the `Swift_Mailer` instance with a custom `Swift_Transport`.
-You can configure:
-- `subject` - The subject of the email sent
-- `from` - The email address set as sender
-- `body` - The body of the email
-- `transport` - The transport to use. For example if you want to use your gmail account or any other SMTP account. The value should be an instance of `Swift_Tranport`
-- `ignore_empty_output` - If this is set to `true`, jobs that return no output won't fire any email.
-
-The configuration can be set "globally" for all the scheduler commands, when creating the scheduler.
-
-```php
-$scheduler = new Scheduler([
-    'email' => [
-        'subject' => 'Visitors count',
-        'from' => 'cron@email.com',
-        'body' => 'This is the daily visitors count',
-        'transport' => Swift_SmtpTransport::newInstance('smtp.gmail.com', 465, 'ssl')
-            ->setUsername('username')
-            ->setPassword('password'),
-        'ignore_empty_output' => false,
-    ]
-]);
-```
-
-Or can be set on a job per job basis.
-
-```php
-$scheduler = new Scheduler();
-
-$scheduler->php('myscript.php')->configure([
-    'email' => [
-        'subject' => 'Visitors count',
-    ]
-]);
-
-$scheduler->php('my_other_script.php')->configure([
