 ## Self reminder, implement this feature. It'd be helpful. 
 
-### Update: 6 Oct. 2025 
-We now have storable arguments. Now we need to implement the on_parse_done callbacks, to achieve this feature.
+### Update: 29 March. 2026
+Help text is clear, supports multi convention print, also provides hints for types that provides the hints in the traits.
+Positional argument support is here. Also we now have some tests to ensure the library works as intended. 
+Also introduce package cmake config to enable other developers to install the library and link against their executables.
