This pull request fixes a factual error in the current getting started documentation.
The current version is recommending setting a reverse DNS record for a server in order to allow to SSH into it using a domain name instead of an IP address. However, this is the whole purpose of a DNS record * (without "reverse").
DNS translates a hostname ("domain") to an IP address (which is what we want here).
Reverse DNS does the exact opposite: Translating an IP address back to a hostname which is e.g. required for running a mail server but is completely unrelated to reaching a server by its hostname/domain.
