What is it?
Tmux is a terminal multiplexer; it allows you to create several "pseudo terminals" from a single terminal. This is very useful for running multiple programs with a single connection, such as when you're remotely connecting to a machine using SSH.
Tmux also decouples your programs from the main terminal, protecting them from accidental disconnecting. You can detach tmux from the current terminal, and all your programs will continue to run safely in the background. Later, you can reattach tmux to the same or a different terminal.
How do you use it?
Tmux uses many keyboard shortcuts that are triggered by pressing the "prefix" combination which by default is Ctrl+B. Going forward $ represents a normal command while : represents inside a tmux session using the prefix combination followed by the : and the rest of the command.
