+
+### Overview
+
+Allegro adapter: banner-only, OpenRTB 2.5, default endpoint `https://dsp.allegro.pl/prebid`, TTL 360s, net revenue true.
+
+### Quick Use
+
+Minimal ad unit:
+
+```javascript
+var adUnits = [{
+    code: 'slot-1',
+    mediaTypes: {banner: {sizes: [[300, 250]]}},
+    bids: [{bidder: 'allegro'}]
+}];
+```
+
+Request bids as usual with `pbjs.addAdUnits` and `pbjs.requestBids`.
+
+### Optional Config
+
+```javascript
+pbjs.setConfig({
+    allegro: {
+        bidderUrl: 'https://prebid.rtb.allegrogroup.com/v1/rtb/prebid/bid', // override if needed
+        convertExtensionFields: true,              // map ext -> [com.google.doubleclick.*]
+        triggerImpressionPixel: false              // fire win pixel if true
+    }
+});
+```
+
+### What It Does
+
+1. Builds standard OpenRTB banner requests.
+2. (Optional) Renames common `ext` objects to DoubleClick-style extension proto fields for downstream systems.
+3. Converts numeric flags (`dnt`, `sua.mobile`, `test`, etc.) to booleans.
+4. On bid win (if enabled) fires `burl`.
