+## Submitting useful bug reports
+
+Please search existing issues first to make sure this is not a duplicate.
+Every issue report has a cost for the developers required to field it; be
+respectful of others' time and ensure your report isn't spurious prior to
+submission. Please adhere to [sound bug reporting principles](http://www.chiark.greenend.org.uk/~sgtatham/bugs.html).
+
+## Development ideology
+
+Truths which we believe to be self-evident:
+
+- **It's an asynchronous world.**  Be wary of anything that undermines
+   async principles.
+
+- **The answer is not more options.**  If you feel compelled to expose
+   new preferences to the user it's very possible you've made a wrong
+   turn somewhere.
+
+- **There are no power users.** The idea that some users "understand"
+   concepts better than others has proven to be, for the most part, false.
+   If anything, "power users" are more dangerous than the rest, and we
+   should avoid exposing dangerous functionality to them.
+
+## Code style
+
+The amphp project adheres to the PSR-2 style guide with the exception that
+opening braces for classes and methods must appear on the same line as
+the declaration:

+# phpunit-util
+
+![License](https://img.shields.io/badge/license-MIT-blue.svg?style=flat-square)
+
+`amphp/phpunit-util` is a small helper package to ease testing with PHPUnit in combination with the [`amp`](https://github.com/amphp/amp) concurrency framework.
+
+**Required PHP Version**
+
+- PHP 7.0+
+
+**Installation**
+
+```bash
+composer require --dev amphp/phpunit-util
+```
+
+**Usage**
+
+Currently, this package only provides a PHPUnit `TestListener` to reset the global event loop after each test. By adding the listener to your PHPUnit configuration, each test will be executed with a completely new event loop instance.
+
+```xml
+<phpunit>
+    <!-- ... -->
+
+    <listeners>
+        <listener class="Amp\PHPUnit\LoopReset" />
+    </listeners>
+
+    <!-- ... -->
+</phpunit>
+```
