+Variables
+---------
+
+Please note that if you use this agent, the variables will only be visible to
+other instances of zsh. Should you use a non-shell mail user agent such as
+thunderbird, make sure it inherits the variables. For an example how to
+achieve this, have a look at issue #419 in the [issue tracker][2].
