-# zshmux
-
-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 will just automatically attach the session to the current shell.

-## How to get zshmux
-
-If you use Arch Linux, zshmux is available on the AUR
-
-Manual installation:
-  - Download and extract this archive
-        $ curl "https://download.huck.website/zshmux-[VERSION].tar.gz"
-        $ tar -xzvf zshmux-[VERSION].tar.gz
-  - Install:
-        $ cd zshmux-[VERSION]
-        # mkdir /usr/lib/zshmux
-        # cp zshmux.zsh /usr/lib/zshmux
-
-Once you've gotten zshmux, add this snippet to your zshrc:
-        [[ -d /usr/lib/zshmux ]] && source /usr/lib/zshmux/zshmux.zsh
-  
--Open a new shell
