 These steps should run Sphinx in your shell and create HTML in the `build/html/`

+The build for Merlin is unique because the support matrix is generated during

+The build reads the `docs/data.json` file and creates several RST snippet files

+The `docs/data.json` file is updated by the `docs-smx-data` GitHub workflow.

+### Remove a field from the JSON
