+### Signature Auth (Assemblies)
 
 <dfn>Signature Authentication</dfn> is done by the PHP SDK by default internally so you do not need to worry about this :)
 
+### Signature Auth (Smart CDN)
+
+You can use the `signedSmartCDNUrl` method to generate signed URLs for Transloadit's [Smart CDN](https://transloadit.com/services/content-delivery/):
+
+```php
+<?php
+require 'vendor/autoload.php';
+
+use transloadit\Transloadit;
+
+$transloadit = new Transloadit([
+  'key'    => 'MY_TRANSLOADIT_KEY',
+  'secret' => 'MY_TRANSLOADIT_SECRET',
+]);
+
+// Basic usage
+$url = $transloadit->signedSmartCDNUrl(
+  'your-workspace-slug',
+  'your-template-slug',
+  'avatars/jane.jpg'
+);
+
+// Advanced usage with custom parameters and expiry
+$url = $transloadit->signedSmartCDNUrl(
+  'your-workspace-slug',
+  'your-template-slug',
+  'avatars/jane.jpg',
+  ['width' => 100, 'height' => 100],  // Additional parameters
+  1732550672867,                      // Expiry date in milliseconds since epoch
+);
+
+echo $url;
+```
+
+The generated URL will be in the format:
+
+```
+https://{workspace-slug}.tlcdn.com/{template-slug}/{input-field}?{query-params}&sig=sha256:{signature}
+```
+
+Note that:
+
+- The URL will expire after the specified time (default: 1 hour)
+- All parameters are properly encoded
+- The signature is generated using HMAC SHA-256
+- Query parameters are sorted alphabetically before signing
+

-## Versioning
+### Testing
+
+#### Basic Tests
+
+```bash
+make test
+```
+
+#### System Tests
+
+System tests require:
+
+1. Valid Transloadit credentials in environment:
+
+```bash
+export TRANSLOADIT_KEY='your-auth-key'
+export TRANSLOADIT_SECRET='your-auth-secret'
+```
+
+Then run:
+
+```bash
+make test-all
+```
+
+#### Node.js Reference Implementation Parity Assertions
+
+The SDK includes assertions that compare URL signing with our reference Node.js implementation. To run these tests:
+
+1. Requirements:
+
+   - Node.js installed
+   - tsx installed globally (`npm install -g tsx`)
+
+2. Install dependencies:
+
+```bash
+npm install -g tsx
+```
+
+3. Run the test:
+
+```bash
+export TRANSLOADIT_KEY='your-auth-key'
+export TRANSLOADIT_SECRET='your-auth-secret'
+TEST_NODE_PARITY=1 make test-all
+```
+
+CI opts-into `TEST_NODE_PARITY=1`, and you can optionally do this locally as well.
