question about document

[James]

Hello,
    At https://kafka.apache.org/intro, I found a sentence:
    Each partition has one server which acts as the "leader" and zero or more 
servers which act as "followers". 
    In my opinion, it is possible that more than one brokers exist on a machine 
with different ports and different broker.id, so I think the below is more 
appropriate:
      Each partition has one broker which acts as the "leader" and zero or more 
brokers which act as "followers". 
Thank you!
