Currently, the documentation for ClusterLogging explicitly recommends using Vector as the LogCollector, but does not provide any instructions on how to do this. I have a customer who ended up needing Black Belt support due to confusion of a mixture of FluentD and Vector information in the docs.

A clear page explaining how to enable Vector and LokiStack in the docs would be extremely helpful for customers attempting to get started with logging:
