 Here profile *host1* contains all the dotfiles defined for *host2* plus `f_xinitrc`.
 
+For more advanced use-cases variables (`variables` and `dynvariables`) can be used
+to specify the profile to include in a profile
+
+For example:
+```yaml
+variables:
+  var1: "john"
+dynvariables:
+  d_user: "echo $USER"
+profiles:
+  profile_john:
