+### Data types
+
+BigQuery supports the following data types: STRING, BYTES, INTEGER, FLOAT,
+NUMERIC, BOOLEAN, TIMESTAMP, DATE, TIME, DATETIME and GEOGRAPHY.
+All possible values are described at
[https://cloud.google.com/bigquery/docs/reference/standard-sql/data-types]
(https://cloud.google.com/bigquery/docs/reference/standard-sql/data-types).
+BigQueryIO allows you to use all of these data types. The following examples
+shows the correct format for data types used when reading from and writing to
+BigQuery:

Review comment:
Hi @melap - does the code snippet change formatting look good to you? For
some reason we don't see it in the preview.

> BYTES is one of the Datatypes supported by Google Cloud BigQuery, and Apache
> Beam BigQuery IO connector.
> Current implementation of BigQuery connector in Java and Python SDKs expects
> that users base64-encode bytes before passing them to BigQuery IO, see
> discussion on dev: [1]
> This needs to be reflected in public documentation, see [2-4]
> cc: [~juta] [~chamikara] [~pabloem]
> cc: [~lostluck] [~kedin] FYI and to advise whether similar action needs to be
