+### Dataset Summary
+
+The WikiTableQuestions dataset is a large-scale dataset for the task of question answering on semi-structured tables.
+
+### Supported Tasks and Leaderboards
+
+question-answering, table-question-answering
+
+### Languages
+
+en
+
+## Dataset Structure
+
+### Data Instances
+
+#### default
+
+- **Size of downloaded dataset files:** 29.27 MB
+- **Size of the generated dataset:** 47.90 MB
+- **Total amount of disk used:** 77.18 MB
+
+An example of 'validation' looks as follows:
+```
+{
+    "id": "nt-0",
+    "question": "what was the last year where this team was a part of the usl a-league?",
+    "answers": ["2004"],
+    "table": {
+        "header": ["Year", "Division", "League", ...], 
+        "name": "csv/204-csv/590.csv", 
+        "rows": [
+           ["2001", "2", "USL A-League", ...],
+           ["2002", "2", "USL A-League", ...], 
+           ...
+        ]
+    }
+}
+```
+
+### Data Fields
+
+The data fields are the same among all splits.
+
+#### default
+- `id`: a `string` feature.
+- `question`: a `string` feature.
+- `answers`: a `list` of `string` feature.
+- `table`: a dictionary feature containing:
+  - `header`: a `list` of `string` features.
+  - `rows`: a `list` of `list` of `string` features:
+  - `name`: a `string` feature.
