+# Flytekit BigQuery Plugin
+
+BigQuery enables us to build data-intensive applications without operational burden. Flyte backend can be connected with the BigQuery service. Once enabled, it can allow you to query a BigQuery table.
+
+To install the plugin, run the following command:
+
+```bash
+pip install flytekitplugins-bigquery
+```
+
+To configure BigQuery in the Flyte deployment's backend, follow the [configuration guide](https://docs.flyte.org/en/latest/deployment/plugin_setup/gcp/bigquery.html#deployment-plugin-setup-gcp-bigquery).
