+## Data Organization
+
+Data is organized as parquet shards by split and project:
+```
+data/
+├── <split>/
+│   └── <project_name>/
+│       └── <timestamp>-<shard>.parquet
+```
+
+The HuggingFace Hub automatically merges all parquet files when loading the dataset.
+
+## Usage
+
+```python
+from datasets import load_dataset
+
+# Load entire dataset
+dataset = load_dataset("jwidmer/line-test-cache") 
+
+# Load specific split
+train_dataset = load_dataset("jwidmer/line-test-cache", split="train")
+```
