Lattices reaches other machines in two separate ways. A **host** accepts
`lats` commands from this Mac over the network. A **visit** lends this Mac's
mouse and keyboard to another machine when you push the pointer past a
screen edge. The two are paired separately. This page sets up each one and
then covers the display commands that work with both.

Both ways go through the host's gateway, which binds only to the host's
Tailscale address. Install Tailscale on every machine first. Macs need the
Lattices app; Linux machines need the separate
[Linux install](/lattices/docs/install-linux).

The examples use two Macs, `mini` (this one) and `air`, and a Linux box,
`archie`.
