+Rate Limiter Component
+======================
+
+The Rate Limiter component provides a Token Bucket implementation to
+rate limit input and output in your application.
+
+Getting Started
+---------------
+
+```
+$ composer require symfony/rate-limiter
+```
+
+```php
+use Symfony\Component\RateLimiter\Storage\InMemoryStorage;
+use Symfony\Component\RateLimiter\RateLimiterFactory;
+
+$factory = new RateLimiterFactory([
+    'id' => 'login',
+    'policy' => 'token_bucket',
+    'limit' => 10,
+    'rate' => ['interval' => '15 minutes'],
+], new InMemoryStorage());
+
+$limiter = $factory->create();
+
+// blocks until 1 token is free to use for this process
+$limiter->reserve(1)->wait();
+// ... execute the code
+
+// only claims 1 token if it's free at this moment (useful if you plan to skip this process)
+if ($limiter->consume(1)->isAccepted()) {
+   // ... execute the code
+}
+```
