+# Instructions
+# ------------
+#
+# 1. Install this script and give it execute permission somewhere in your PATH.
+#    For example:
+#
+#    $ mkdir -p ~/bin
+#    $ wget https://raw.github.com/jipumarino/tmux-zoom/master/tmux-zoom.sh -O ~/bin/tmux-zoom.sh
+#    $ chmod +x ~/bin/tmux-zoom.sh
+# 
+# 2. Add a shortcut in your ~/.tmux.conf file:
+#
+#    bind C-k run "tmux-zoom.sh"
+#
+# 3. When using this shortcut, the current tmux pane will open in a new window by itself.
+#    Running it again in the zoomed window will return it to its original pane. You can have
+#    as many zoomed windows as you want.
