+The train split is the machine translated train data from SQuAD v1.1. 
+The validation split and the test split are from MLQA.
+
+We created this particular version with the following code:
+```python
+import datasets
+
+# Machine translated train data from SQuAD v1.1.
+mlqa_train_dev = datasets.load_dataset("facebook/mlqa", "mlqa-translate-train.vi")
+# Original validation and test data from MLQA
+mlqa_val_test = datasets.load_dataset("facebook/mlqa", "mlqa.vi.vi")
+
+# Merge and create our version
+mlqa = mlqa_train_dev
+mlqa["validation"] = mlqa_val_test["validation"]
+mlqa["test"] = mlqa_val_test["test"]
