 ## Dataset Loading
 
-We can load the full data using:
+### Full Dataset Load
 
 ```py
 from datasets import load_dataset
 dataset = load_dataset("MagmaAI/Magma-OXE-ToM", streaming=True, split="train")
 ```
 
+### Individual Dataset Load
 or specify a dataset by:
 
 ```py
 from datasets import load_dataset
 dataset = load_dataset("MagmaAI/Magma-OXE-ToM", data_dir="austin_buds_dataset_converted_externally_to_rlds", streaming=True, split="train")
+```
+
+### Sample Decoding
+
+```py
+# Helper function to deserialize binary fields
+def deserialize_array(bytes_data):
+    return pickle.loads(bytes_data)
+
+# Helper function to convert binary image data to PIL Image
+def bytes_to_image(image_bytes):
+    return Image.open(io.BytesIO(image_bytes))
+
+for i, example in enumerate(dataset):   
+    # decode the image: 256 x 256 x 3
+    image = bytes_to_image(example['image'])
+    # decode action: 1 x 7
+    action = deserialize_array(example['action'])
+    # decode trace: 1 x 17 x 256 x 2
+    trace = deserialize_array(example['trace'])
+    # decode trace visibility: 1 x 17 x 256 x 1
+    trace_visibility = deserialize_array(example['trace_visibility'])
 ```
