+## Loading the dataset with a specific configuration
+
+There are 3 different OCR versions to choose from with their original format or standardized DUE format, as well as the option to load the documents as filepaths or as binaries (PDF).
+To load a specific configuration, pass a config from one of the following:
+
+```python
+#{bin_}{Amazon,Azure,Tesseract}_{original,due}
+['Amazon_due', 'Amazon_original', 'Azure_due', 'Azure_original', 'Tesseract_due', 'Tesseract_original', 
+'bin_Amazon_due', 'bin_Amazon_original', 'bin_Azure_due', 'bin_Azure_original', 'bin_Tesseract_due', 'bin_Tesseract_original']
+```
+
+```python
+from datasets import load_dataset
+
+ds = load_dataset("jordyvl/DUDE_loader", 'Amazon_original')
+```
