+Monolog handler that interfaces with PHP Quick Profiler
+
+## Installation
+It's recommended that you use [Composer](https://getcomposer.org/) to install MonologPQP Handler.
+
+```bash
+$ composer require jacobemerick/monolog-pqp
+```
+
+This will install the handler and dependencies. It requires PHP 5.3.0 or newer.
+
+## Usage
+This is a handler for Monolog that will send logs and exceptions to PHP Quick Profiler. For more information about the profiler see [jacobemerick/pqp](https://github.com/jacobemerick/pqp).
+
+```php
+$console = new Particletree\Pqp\Console();
+$profiler = new Particletree\Pqp\PhpQuickProfiler();
+$profiler->setConsole();
+
+$logger = new Monolog\Logger('web');
+$handler = new Jacobemerick\MonologPqp\PqpHandler($console);
+$logger->pushHandler($handler);
+
+$logger->addDebug('PQP handler added to Monolog');
+```
+
+The default logging level for this handler is set to `Monolog\Logger::DEBUG`. For more information about this, or how to customize the format displayed in the profiler, see [Seldaek/monolog](https://github.com/Seldaek/monolog).
+
+### Errors
+PHP Quick Profiler handles exceptions separately, displaying more information about them and tagging as 'error'. If you simply do `$logger->error()` you will log the message but not get the extra sugar. The best way to handle this is by using Monolog as an exception handler.
+
+```php
+$logger = new Monolog\Logger('web');
+$handler = new Jacobemerick\MonologPqp\PqpHandler($console);
+$logger->pushHandler($handler);
+
+Monolog\ErrorHandler::register($logger);
+throw new Exception('testing');
+```
+
+This will trigger the `logError` method in the profiler and display additional data about the problem.
