Hi @morningman
Thanks for your contribution. Please add a record of this doc page into the docs.json file so it will be listed in the navigation.

@morningman
Please add the information from Apache Doris' README file into the documentation, such as the ssl parameters. After that, please copy the documentation page into this README, such that both the MDX doc page and the README file have the same content.
