 Tmuxify your Tmux. Create, edit, manage and load complex Tmux session, window
 and pane configurations with ease.
 
 In short, Tmuxifier allows you to easily create, edit, and load "layout"
 files, which are simple shell scripts where you use the `tmux` command and

+## Tips
+
+### iTerm2 Integration
+
+Tmuxifier supports iTerm2's [Tmux integration][]. It can be used in two ways:
+
+- Passing `-CC` as a second argument to the `load-session` command. For
+example:
+
+        tmuxifier load-session my-awesome-session -CC
+
+- Setting the `TMUXIFIER_TMUX_ITERM_ATTACH` environment variable to `-CC`
+  before calling the `load-session` command.
