+```bash
+# tmux is a terminal multiplexer: it enables a number of terminals to be
+# created, accessed, and controlled from a single screen. tmux may be detached
+# from a screen and continue running in the background, then later reattached.
+
+# Once you feel comfortable manipulating tmux to suit your needs, I strongly
+# suggest you read the man pages, as there are TONS of features I’m not going
+# to go over.
+
+
+# We’ll start of with managing tmux from a terminal, then introduce you to the
+# keybinds:
+
+ tmux | tmux new # Create an unamed session
+ -s "Session" # Create named session
+ -n "Window" # Create named Window
+ -c "/dir" # Start in target directory
+
+ tmux attach # Attach last/available session
+ -t "#" # Attach target session
+ -d # Detach the session from other instances
+
+ tmux ls # List open sessions
+
+ kill-session # Kill current session
+ -t "#" # Kill target session
+ -a # Kill all sessions
+ -a -t "#" # Kill all sessions but the target
+
+
+
+## Key Bindings
+
+# The method of controlling an attached tmux session is fairly simple, but
+# there are two keys we will see repeated throughout this write-up (as well as
+# the man pages).
+
+ (C-b) == Ctrl + b THEN ? to list all keybinds
+
+# The default keybinds are as follows:
+
+ C-b # Send the prefix key (C-b) through to the application.
+ C-o # Rotate the panes in the current window forwards.
+ C-z # Suspend the tmux client.
+ ? # List all key bindings.
+ : # Enter the tmux command prompt.
+ r # Force redraw of the attached client.
+
+ c # Create a new window.
+ $ # Rename the current session.
+ , # Rename the current window.
+
+ ! # Break the current pane out of the window.
+ % # Split the current pane into two, left and right.
+ " # Split the current pane into two, top and bottom.
+
+ n # Change to the next window.
+ p # Change to the previous window.
+ { # Swap the current pane with the previous pane.
+ } # Swap the current pane with the next pane.
+
+ s # Select a new session for the attached client interactively.
+ w # Choose the current window interactively.
+ 0 to 9 # Select windows 0 to 9.
+
+ d # Detach the current client.
+ D # Choose a client to detach.
+
+ & # Kill the current window.
+ x # Kill the current pane.
+
+ Up, Down # Change to the pane above, below, left, or right.
+ Left, Right
+
+ M-1 to M-5 # Arrange panes:
+ # 1) even-horizontal
+ # 2) even-vertical
+ # 3) main-horizontal
+ # 4) main-vertical
+ # 5) tiled.
+
+ C-Up, C-Down # Resize the current pane in steps of one cell.
+ C-Left, C-Right
+
+ M-Up, M-Down # Resize the current pane in steps of five cells.
+ M-Left, M-Right

+### Configuring ~/.tmux.conf
+
+ tmux.conf can be used to set options automatically on start up, much
+like how .vimrc or init.el are used.
+
+```bash
+# Example tmux.conf
+# http://dev.gentoo.org/~wired/conf/tmux.conf
+# http://wiki.gentoo.org/wiki/Tmux
+# https://wiki.archlinux.org/index.php/Tmux
