 If you don't want to download that stuff manually, navigate to the `examples` directory and issue the `./example` command. This will download the necessary files and run some detections.
 
-### Async
-By default, darknet.js will run the detections synchronously. If this isn't your style, you can run detections asynchronously, using the `detectAsync` method. 
-```typescript
-darknet.detectAsync('/image/of/a/dog.jpg')
-    .then(detections => console.log(detections));
-```
-At this time, async detections cannot be run in parallel and attempting to will cause your detections to be incorrect. The `DarknetExperimental` class has serial async. It is intended to eventually replace the original `Darknet` class:
-```typescript
-import { DarknetExperimental } from 'darknet';
-
-const darknet = new DarknetExperimental(config);
-
-darknet.detectAsync('/image/of/a/dog.jpg')
-  .then(detections => console.log(detections));
-  
-darknet.detectAsync('/image/of/a/cat.jpg')
-  .then(detections => console.log(detections));
-
-darknet.detectAsync('/image/of/an/eagle.jpg')
-  .then(detections => console.log(detections));
