+## Strings for translation
+
+To support gettext translation use Zuper's functions for noticing messages to console:
+
+ - `notice` (green visible header)
+ - `act` (bullet point information)
+ - `warning` (orange warning, non fatal)
+ - `error` (fatal error) followed by `zerr` and `zshexit`
+
+Each string should not contain any variable, but pointers to
+variables, then be followed by actual variables as arguments. So for
+instance:
+
+```
+notice "Starting to bake files in ::1 directory:: for target ::2 arch::" $dir $arch
+```
+
+This will print the string with variables in it, but string will
+contain references to them. This is so that gettext translations will
+point to the same string even in case of name of variables changing.
