+
+Utopia Telemetry is a powerful Telemtry library. This library is aiming to be as simple and easy to learn and use. This library is maintained by the [Appwrite team](https://appwrite.io).
+
+Although this library is part of the [Utopia System](https://github.com/utopia-php) project it is dependency free and can be used as standalone with any other PHP project or framework.
+
+## Getting Started
+
+Install using composer:
+
+```bash
+composer require utopia-php/telemetry
+```
+
+Init in your application:
+
+```php
+<?php
+
+require_once __DIR__ . '/vendor/autoload.php';
+
+// Create a Telemetry instance using OpenTelemetry adapter.
+use Utopia\Telemetry\Adapter\OpenTelemetry;
+
+$telemetry = new OpenTelemetry('http://localhost:4138', 'namespace', 'app', 'unique-instance-name');
+$counter = $telemetry->createUpDownCounter('http.server.active_requests', '{request}');
+
+$counter->add(1);
+$counter->add(2);
+
+// Periodically collect metrics and send them to the configured OpenTelemetry endpoint.
+$telemetry->collect();
+
+// Example using Swoole
+\Swoole\Timer::tick(60_000, fn () => $telemetry->collect());
+```
+
+## System Requirements
+
+Utopia Framework requires PHP 8.0 or later. We recommend using the latest PHP version whenever possible.
