 'bin_Amazon_due', 'bin_Amazon_original', 'bin_Azure_due', 'bin_Azure_original', 'bin_Tesseract_due', 'bin_Tesseract_original']
 ```
 
+Loading the dataset:
 ```python
 from datasets import load_dataset
 
 ds = load_dataset("jordyvl/DUDE_loader", 'Amazon_original')
 ```
 
+This dataset repository contains helper functions to convert the dataset to ImDB (image database) format. 
+We advise to clone the repository and run it according to your preferences (OCR version, lowercasing, ...).
+When running the above data loading script, you should be able to find the extracted binaries under the [HF_CACHE](https://huggingface.co/docs/datasets/cache):  
+`HF_CACHE/datasets/downloads/extracted/<hash>/DUDE_train-val-test_binaries`, which can be reused for the `data_dir` argument.
+
+For example: 
+
+```bash
+python3 DUDE_imdb_loader.py \
+--data_dir ~/.cache/huggingface/datasets/downloads/extracted/7adde0ed7b0150b7f6b32e52bcad452991fde0f3407c8a87e74b1cb475edaa5b/DUDE_train-val-test_binaries/
