NAT hotspot rules

According to the wiki, /ip firewall nat has a hotspot property

hotspot (auth | from-client | http | local-dst | to-client; Default: )

but it gives no documentation on how this works. The Hotspot wiki doesn’t appear to give any explanation either. All I have to go on is the default NAT rules added into the table after enabling the hotspot.

Does anyone have any examples/tutorials/etc they can share (or give me a quick rundown) so I can wrap my head around this? I’m getting into some tricky configs, and I am fairly sure this property is the key to getting some things working correctly.
