-## YOLOv5 and other YOLO versions
+## Supported YOLO Versions: YOLOv5, YOLO11, and others
 
-YOLOv8 models have been successfully tested with this ML backend.
+- **YOLOv5**: This model is supported for object detection tasks. Make sure to specify `model_path="yolov5nu.pt"` (don't forget the **`u`**) to use the YOLOv5 model.
+
+- **YOLOv8**: These models have been successfully tested with the current ML backend. Check the full list of [v8 models here](https://docs.ultralytics.com/models/yolov8/#supported-tasks-and-modes).
+
+- **YOLO11**: YOLO11 models have also been successfully tested with this ML backend. Check the full list of [v11 models here](https://docs.ultralytics.com/models/yolo11/#supported-tasks-and-modes).
+
+    **Warning 1**: You must upgrade the `ultralytics` package to the latest version (`pip install -U ultralytics`) or rebuild the ML backend Docker from scratch (`docker-compose build --no-cache`) if you used it before the latest Ultralytics update on **Monday, September 30, 2024**.
+
+    **Warning 2**: YOLO11 models do not use the `v` in their naming convention. For example, use **`yolo11n.pt`** instead of `yolov11n.pt`, unlike the naming convention in YOLOv8.
+
+- For a full list of supported YOLO versions and models, refer to the Ultralytics documentation:
+  [Ultralytics Supported YOLO Models](https://docs.ultralytics.com/models/)
+
+    **Note**: Some YOLO models listed in the Ultralytics documentation have not been tested with this ML backend, but they might still work.
 
-Attempts to run YOLOv5 were unsuccessful without modifications. 
-It may be possible to run it by applying some changes, such as installing additional dependencies. 
-The same applies to other YOLO models.
 
 ## Your own custom YOLO models

 You can integrate your own custom-trained YOLOv8 models with the YOLO ML backend for Label Studio. 
 Follow these detailed steps to set up your custom model in the ML backend Docker:
 
+### Step 0: Install Label Studio and clone this Github repository
+
+1. Install and run Label Studio (or see [more ways here](https://labelstud.io/guide/install)). 
+
+```
+pip install label-studio
+label-studio
+```
+
+2. Clone the Label Studio ML backend repository and go to the `yolo` example folder:
+
+```
+git clone https://github.com/HumanSignal/label-studio-ml-backend.git
+cd label-studio-ml-backend/examples/yolo
+```
+
 ### Step 1: Prepare your custom YOLOv8 model
 
 Ensure that your custom YOLOv8 model is saved as a `.pt` file, which is the standard format for PyTorch models.
