Translate links in Drupal menu page
In General Usage of Contributed Modules first steps to use any module is


Read Documentation of Project Page in D.O . You will find the link in the right side bar.





Readme or Install files inside Module Folder
Still if you are unable to figure out.. Visit .module file and focus on hook_menu implementation which lists menu paths as keys of $items array.. By visiting those pages you will get a chance to see configuration pages given by that particular module.


In your case


Enable i18n_menu module which has following module dependencies. I enabled using drush which automatically downloads and enabled below modules. In your case make sure below modules are present in your instance.


The following extensions will be enabled: i18n_menu, i18n_translation, i18n_string, variable, locale, i18n


Once you enable you can see "Translate" setting in any menu page. I just verified no other changes are required. Just clear cache once you enable module in case.
