No explanation on how to use this

[RomanSC]

This looks awesome, I know enough to set up an i3 config file but...

How do I use this? Something in my i3 config file or a startup process?

Thanks,
Roman

"exec i3session restore" in my config, and then "exec i3session save" before any commands for logging out or shutting down?
