MQTT - explanation for beginner

[Homer]

G'day everyone!

When I've been searching the net for home automation ideas, I often come across references to MQTT. I've tried to find info on it that is simple and clear like Mysensors is explained here. Does someone know of a guide or something that will help explain everything about this?

Thanks!
