+"""Google Cloud Spanner IO
+
+This is an experimental module for reading and writing data from Google Cloud
+Spanner. Visit: https://cloud.google.com/spanner for more details.
+
+To read from Cloud Spanner apply ReadFromSpanner transformation. It will
+return a list, where each element represents an individual row returned from
+the read operation. Both Query and Read APIs are supported.
+
+ReadFromSpanner relies on the ReadOperation objects which is exposed by the
+SpannerIO API. ReadOperation holds the immutable data which is responsible to
+execute batch and naive reads on spanner cloud. This is done for more
+convenient programming.
+
+ReadFromSpanner read from cloud spanner by providing the either 'sql' param
