+- Updated the Data Loader CLI tool to accept a base_url, a data directory, a custom collection id, and an option to use bulk insert. [#218](https://github.com/stac-utils/stac-fastapi-elasticsearch-opensearch/pull/218)

+- There is [Postman](https://documenter.getpostman.com/view/12888943/2s8ZDSdRHA) documentation here for examples on how to run some of the API routes locally - after starting the elasticsearch backend via the docker-compose.yml file.
+- The `/examples` folder shows an example of running stac-fastapi-elasticsearch from PyPI in docker without needing any code from the repository. There is also a Postman collection here that you can load into Postman for testing the API routes.
