Community rules
Many rules have been developed and published by the community. Follow this documentation to use them in your project.

Migration rules
Migration rules make it easier for library users to cope with deprecations and breaking changes.
Official migrations provided by library authors are not advertized here as they are usually well documented in the project itself. Note that Scala Steward keeps track of many of them, to provide a seamless experience to library users opting-in for the service.
