Expanders Docs moved to exchange.stars-end.net

The auto-generated documentation on the Expanders and various other expander bundles, has been moved to exchange.stars-end.net.

The exchange site is, similar to this documentation, based on Jekyll and can be found in its own repository (normalizedsystems/exchange-docs).

The goal is to make a dedicated page to share expander bundles and hopefully provide some useful documentation. At the moment, the automatically generated documentation can seem a bit rough. We will continue to update the report-expanders to improve the insight into the expander bundles and allow for better integration with existing documentation.
