+```shell
+$ tmux new -s 'example_session_name'
+```
+
+Creates a new tmux session with the name 'example_session_name' which is very powerful and will
+exist even if you close out of the terminal.
+
+Once you launch use **\<Ctrl + ">** to split the window horizontally or **\<Ctrl + %>** for
+vertically split and moving between windows with **\<Ctrl - Vim_Direction>**
+You can detach and go back to shell at any time with **\<Ctrl + d>** then reattach later with
+**tmux new-s 'example_session_name'**. If you forget the name a simple **tmux ls** show running
+sessions.
