 If a new shell is launched, *zshmux* quickly checks if there are any tmux sessions, or if the current shell is already in a tmux instance.
 If you are not already in a tmux session *zshmux* will list all currently active sessions, and ask if you want to attach a currently running session, or make a new session in the shell.
+If there is only one tmux session running and not attached to any clients, *zshmux* just automatically attach the session to the current shell.
+
 
 ## How to use:
 -Clone this repository: `git clone https://github.com/huboles/zshmux`
 
--Source *zshmux* in your .zshrc: `source <path-to-zshmux>/zshmux/zshmux.zsh`
+-Source *zshmux* in your .zshrc: `[[ -e <path-to-zshmux>/zshmux/zshmux.zsh ]] && . <path-to-zshmux>/zshmux/zshmux.zsh`
 
 -Open a new shell
