   * Add the source to writing functions of each destination. Here are examples for [pandas](https://github.com/sfu-db/connector-x/blob/main/connectorx-python/src/pandas/mod.rs) and [arrow](https://github.com/sfu-db/connector-x/blob/main/connectorx-python/src/arrow.rs)
 * Add corresponding unit tests under `connectorx/tests` for Rust and `connectorx-python/connectorx/tests` for Python
+* Add the new source to the [docs](./docs/)
