> NOTICE: This repository is the restoration of CloudQuery's legacy open source provider \`cq-source-${SOURCE_PROVIDER}\`
> following CloudQuery's [movement of previously open-source plugins to closed-source](https://www.cloudquery.io/blog/cloudquery-official-free-plugins-moving-to-paid).
> For the latest and greatest these plugins have to offer subscribe to the official plugins from the CloudQuery hub. This repo will accept pull requests but generally only exists
> to maintain security updates for the previously open-source plugin.
