+For tmux, the plugin searches for opencode panes **only in the current tmux window** using:
 
 - Current command is `opencode`
 - Pane title contains "opencode"
 - Recent command history contains opencode
 
+For zellij, the plugin searches terminal panes in the **current active tab** and matches panes by command/title containing `opencode`.
+
 This ensures it finds the opencode instance you're actively working with, not some other session.
 
 ## Troubleshooting

 - **Same window**: Ensure opencode is running in a pane in the **same tmux window** as Neovim
 - **Split window**: Use `Ctrl-b %` or `Ctrl-b "` to split and run opencode in one pane
 - **Manual target**: Set `tmux_target = "session:window.pane"` in config to override detection
 - **Verify opencode is running**: Check that opencode is actually running in the current window
