Wiki help needed regarding locking,

You could call this a feature request,
I cannot find out how to lock the system via duration or if you close the lid.
I am using openrc and I have access to slock, xautolock and am using i3-wm.
Can you tell me how to do this and/or add it to the wiki for Gentoo and Hyperbola users.
truthfully slock can solve the first issue, but I want a solution to solve both at once if possible.
I like the minimal approach.
