+### Behavior when running multiple tmux servers
+
+(This is safe to skip if you're always running a single tmux server.)
+
+If you're an advanced tmux user, you might be running multiple tmux servers at
+the same time. Maybe you start the first tmux server with `$ tmux` and then
+later another one with e.g. `$ tmux -S/tmp/foo`.
+
+You probably don't want to "auto restore" the same environment in the second
+tmux that uses `/tmp/foo` socket. You also probably don't want two tmux
+environments both having "auto save" feature on (think about overwrites).
+
+This plugin handles multi-server scenario by giving precedence to the tmux
+server that was first started.
+
+In the above example, the server started with `$ tmux` will do "auto
+restore" (if enabled) and will start "auto saving".
+"Auto restore" or "auto saving" **will not** happen for the second server that
+was started later with the `$ tmux -S/tmp/foo` command. The plugin will
+detect the presence of another server (`$ tmux`) and give it precedence.
