Description

For new roles please include a brief description of what this app does, or what the purpose of this role is. Include a link to the docker container used, the projects home page and a link to the documentation if it exists.

It would be greatly appreciated if you create a sandbox documentation page yourself and do a PR into the docs repo. You, as the person creating the role, have presumably used the thing and are presumably familiar with any setup steps required. Anyone else here would need to research that.

For existing roles, please include a summary of the change and which issue is fixed if any. Please also include relevant motivation and context. List any dependencies that are required for this change.
