+
+## Introduction
+
+> This project is a fork of the excellent [opis/closure: 3.x](https://github.com/opis/closure) package. At Laravel, we decided to fork this package as the upcoming version [4.x](https://github.com/opis/closure) is a complete rewrite on top of the [FFI extension](https://www.php.net/manual/en/book.ffi.php). As Laravel is a web framework, and FFI is not enabled by default in web requests, this fork allows us to keep using the `3.x` series while adding support for new PHP versions.
+
+Laravel Serializable Closure provides an easy and secure way to **serialize closures in PHP**.
+
+## Official Documentation
+
+### Installation
+
+> **Requires [PHP 7.4+](https://php.net/releases/)**
+
+First, install Laravel Serializable Closure via the [Composer](https://getcomposer.org/) package manager:
+
+```bash
+composer require laravel/serializable-closure
+```
+
+### Usage
+
+You may serialize a closure this way:
+
+```php
+use Laravel\SerializableClosure\SerializableClosure;
+
+$closure = fn () => 'james';
+
+// Recommended
+SerializableClosure::setSecretKey('secret');
+
+$serialized = serialize(new SerializableClosure($closure));
+$closure = unserialize($serialized)->getClosure();
+
+echo $closure(); // james;
+```
+
+### Caveats
+
+1. Creating **anonymous classes** within closures is not supported.
+2. Using attributes within closures is not supported.
