+### [Dataset Summary](#dataset-summary)
+
+ComQA is a dataset of 11,214 questions, which were collected from WikiAnswers, a community question answering website.
+By collecting questions from such a site we ensure that the information needs are ones of interest to actual users.
+Moreover, questions posed there are often cannot be answered by commercial search engines or QA technology, making them
+more interesting for driving future research compared to those collected from an engine's query log. The dataset contains
+questions with various challenging phenomena such as the need for temporal reasoning, comparison (e.g., comparatives,
+superlatives, ordinals), compositionality (multiple, possibly nested, subquestions with multiple entities), and
+unanswerable questions (e.g., Who was the first human being on Mars?). Through a large crowdsourcing effort, questions
+in ComQA are grouped into 4,834 paraphrase clusters that express the same information need. Each cluster is annotated
+with its answer(s). ComQA answers come in the form of Wikipedia entities wherever possible. Wherever the answers are
+temporal or measurable quantities, TIMEX3 and the International System of Units (SI) are used for normalization.

+
+## [Dataset Structure](#dataset-structure)
+
+We show detailed information for up to 5 configurations of the dataset.
+
+### [Data Instances](#data-instances)
+
+#### default
+
+- **Size of downloaded dataset files:** 1.59 MB
+- **Size of the generated dataset:** 1.05 MB
+- **Total amount of disk used:** 2.65 MB
+
+An example of 'validation' looks as follows.
+```
+{
+    "answers": ["https://en.wikipedia.org/wiki/north_sea"],
+    "cluster_id": "cluster-922",
+    "questions": ["what sea separates the scandinavia peninsula from britain?", "which sea separates britain from scandinavia?"]
+}
+```
+
+### [Data Fields](#data-fields)
+
+The data fields are the same among all splits.
+
+#### default
+- `cluster_id`: a `string` feature.
+- `questions`: a `list` of `string` features.
+- `answers`: a `list` of `string` features.
+
+### [Data Splits Sample Size](#data-splits-sample-size)
