+#### Continuous saving
 
 After this plugin is installed, `tmux-resurrect` will save environment at the
 interval of 15 minutes. All the saving happens in the background without the
 impact to your workflow.
 
-Requirements / dependencies: `tmux 1.9` or higher, `bash`,
+#### Automatic restore
+
+Last saved environment is automatically restored when tmux server is started.
+Put `set -g @resurrect-auto-restore 'on'` in `tmux.conf` to enable this.
+
+Note: automatic restore happens **exclusively** on tmux server start. No other
+action (e.g. sourcing `tmux.conf`) triggers this.
