+## Usage
+
+### With LibreYOLO
+
+```python
+from libreyolo import LIBREYOLO
+
+# Load a model
+model = LIBREYOLO(model_path="libreyoloXnano.pt")
+
+# Train on this dataset
+model.train(data='path/to/data.yaml', epochs=100)
+```
+
+### Download from HuggingFace
+
+```python
+from huggingface_hub import snapshot_download
+
+# Download the dataset

+
+Roboflow is an end-to-end computer vision platform that helps you
+* collaborate with your team on computer vision projects
+* collect & organize images
+* understand and search unstructured image data
+* annotate, and create datasets
+* export, train, and deploy computer vision models
+* use active learning to improve your dataset over time
+
+For state of the art Computer Vision training notebooks you can use with this dataset,
+visit https://github.com/roboflow/notebooks
+
+To find over 100k other datasets and pre-trained models, visit https://universe.roboflow.com
+
+The dataset includes 2105 images.
+Stomata-cells are annotated in YOLOv8 format.
+
+The following pre-processing was applied to each image:
+* Auto-orientation of pixel data (with EXIF-orientation stripping)
+* Resize to 640x640 (Stretch)
+
+No image augmentation techniques were applied.
