+### Using the Huggingface Datasets
+
+While HF datasets is ideal for tabular datasets it is not a natuaral fit for nested data structures like the OpenAssistant conversation trees.
+Nevertheless we make all messages which can alse be found in the file `2023-04-12_oasst_ready.trees.jsonl.gz` available as parquet train/validation 
+split which is directly loadable by the [Huggingface Datasets](https://pypi.org/project/datasets/).
+
+To load the oasst1 train & validation splits use:
+
+```python
+from datasets import load_dataset
+ds = load_dataset("OpenAssistant/oasst1")
+train = ds['train']      # len(train)=84437 (95%)
+val = ds['validation']   # len(val)=4401 (5%)
+```
+
+The messages appear in depth-first order of the message trees.
