A simple function like the one in [issue #164](https://github.com/SparkPost/php-sparkpost/issues/164#issuecomment-289888237) wraps the SparkPost API and makes it easy to use the API without resolving the composer dependencies.

+## Running with IDEs
+
+When running with `xdebug` under an IDE such as VS Code, you may see an exception is thrown in file `vendor/php-http/discovery/src/Strategy/PuliBetaStrategy.php`:
+
+```
+Exception has occurred.
+Http\Discovery\Exception\PuliUnavailableException: Puli Factory is not available
+```
+
+[This is usual](http://docs.php-http.org/en/latest/discovery.html#puli-factory-is-not-available). Puli is not required to use the library. You can resume running after the exception.
+
+You can prevent the exception, by setting the discovery strategies, prior to creating the adapter object:
+```php
+// Prevent annoying "Puli exception" during work with xdebug / IDE
+// See https://github.com/getsentry/sentry-php/issues/801
