+### Setting Request Options
+
+Use the `options()` method to set any request options supported by the underlying implementation:
+
+```typescript
+import { SmartRequest } from '@push.rocks/smartrequest';
+
+// Set various options
+const response = await SmartRequest.create()
+  .url('https://api.example.com/data')
+  .options({
+    keepAlive: true,           // Enable connection reuse (Node.js)
+    timeout: 10000,            // 10 second timeout
+    hardDataCuttingTimeout: 15000, // 15 second hard timeout
+    // Platform-specific options are also supported
+  })
+  .get();
+```
+
 ### Working with Different Response Types
 
 The API provides a fetch-like interface for handling different response types:
@@ -218,6 +237,49 @@ The response object provides these methods:
 
 Each body method can only be called once per response, similar to the fetch API.
 
+### Important: Always Consume Response Bodies
+
+**You should always consume response bodies, even if you don't need the data.** Unconsumed response bodies can cause:
+- Memory leaks as data accumulates in buffers
+- Socket hanging with keep-alive connections
+- Connection pool exhaustion
+
+```typescript
+// ❌ BAD - Response body is not consumed
+const response = await SmartRequest.create()
+  .url('https://api.example.com/status')
+  .get();
+  
+if (response.ok) {
+  console.log('Success!');
+}
+// Socket may hang here!
+
+// ✅ GOOD - Response body is consumed
+const response = await SmartRequest.create()
+  .url('https://api.example.com/status')
+  .get();
+  
+if (response.ok) {
+  console.log('Success!');
+}
+await response.text(); // Consume the body even if not needed
+```
+
+In Node.js, SmartRequest automatically drains unconsumed responses to prevent socket hanging, but it's still best practice to explicitly consume response bodies. When auto-drain occurs, you'll see a console log: `Auto-draining unconsumed response body for [URL] (status: [STATUS])`.
+
+You can disable auto-drain if needed:
+```typescript
+// Disable auto-drain (not recommended unless you have specific requirements)
+const response = await SmartRequest.create()
+  .url('https://api.example.com/data')
+  .autoDrain(false)  // Disable auto-drain
+  .get();
+  
+// Now you MUST consume the body or the socket will hang
+await response.text();
+```

+### Rate Limiting (429 Too Many Requests) Handling
+
+The library includes built-in support for handling HTTP 429 (Too Many Requests) responses with intelligent backoff:
+
+```typescript
+import { SmartRequest } from '@push.rocks/smartrequest';
+
+// Simple usage - handle 429 with defaults
+async function fetchWithRateLimitHandling() {
+  const response = await SmartRequest.create()
+    .url('https://api.example.com/data')
+    .handle429Backoff()  // Automatically retry on 429
+    .get();
+
+  return await response.json();
+}
+
+// Advanced usage with custom configuration
+async function fetchWithCustomRateLimiting() {
+  const response = await SmartRequest.create()
+    .url('https://api.example.com/data')
+    .handle429Backoff({
+      maxRetries: 5,              // Try up to 5 times (default: 3)
+      respectRetryAfter: true,    // Honor Retry-After header (default: true)
+      maxWaitTime: 30000,         // Max 30 seconds wait (default: 60000)
+      fallbackDelay: 2000,        // 2s initial delay if no Retry-After (default: 1000)
+      backoffFactor: 2,           // Exponential backoff multiplier (default: 2)
+      onRateLimit: (attempt, waitTime) => {
+        console.log(`Rate limited. Attempt ${attempt}, waiting ${waitTime}ms`);
+      }
+    })
+    .get();
+
+  return await response.json();
+}
+
+// Example: API client with rate limit handling
+class RateLimitedApiClient {
+  private async request(path: string) {
+    return SmartRequest.create()
+      .url(`https://api.example.com${path}`)
+      .handle429Backoff({
+        maxRetries: 3,
+        onRateLimit: (attempt, waitTime) => {
+          console.log(`API rate limit hit. Waiting ${waitTime}ms before retry ${attempt}`);
+        }
+      });
+  }
+
+  async fetchData(id: string) {
+    const response = await this.request(`/data/${id}`).get();
+    return response.json();
+  }
+}
+```
+
+The rate limiting feature:
+- Automatically detects 429 responses and retries with backoff
+- Respects the `Retry-After` header when present (supports both seconds and HTTP date formats)
+- Uses exponential backoff when no `Retry-After` header is provided
+- Allows custom callbacks for monitoring rate limit events
+- Caps maximum wait time to prevent excessive delays
