+##### With Conditionals
+
+You may want to control when and/or how plugins should be enabled.
+
+For example, if you want the `tmux-autoattach` plugin to only run on SSH sessions, you could employ a trivial conditional that checks for the `$SSH_TTY` variable. Just make sure to remove the plugin from the larger plugin list.
+
+``` bash
+[ "$SSH_TTY" ] && plugins+=(tmux-autoattach)
+```
+
 #### Using Plugins
 
 Most plugins (should! we're working on this) include a __README__, which documents how to use them.

+*Note* If you prefer to manually start your desktop session using tools like `startx`, you may run into problems starting your desktop session inside of a tmux terminal. You can employ conditionals to control when this plugin should be enabled.
