-Lightweight PSR-17 HTTP Factory mocking implementation tailored to simplify testing. This library mocks HTTP requests and is not intended for use in production.
-
-This library inherits [psr-mock/http-message-implementation](https://github.com/psr-mock/http-message-implementation), therefore also making this a provider of PSR-7.
+**Lightweight mocking library for [PSR-17 HTTP Factory](https://www.php-fig.org/psr/psr-17/) and [PSR-7 HTTP Message](https://www.php-fig.org/psr/psr-7) implementations, tailor-made to help you create test suites that are easier to write and maintain.**

+This library is primarily intended for use in libraries like SDKs that consume PSR implementations without requiring hard dependencies on specific libraries. The library mocks a real-world implementation and strictly adheres to PSR specifications, enabling you to create test suites that are easier to write and maintain. The library also exposes a robust developer API to help you debug and fix test failures substantially faster.
+
+This package is part of the [PSR Mock](https://github.com/psr-mock) suite of mocking libraries.
