when I add a new product asks me to enter the collection to which it belongs, let me know how I can change the name of the collections that come by default?
[KickStart 2] Head on over to Taxonomy (Site Settings, Advanced settings, Structure) and look for Collection. You will find the "To Carry" term there. Simply make your change, or just add in the name you wish to use. The Main Menu is generated by Commerce modules that take those terms that are in active use and auto-create the links. The final step is to edit a product in that collection so that the Main Menu is refreshed. A simple edit , reselect of the name in the Collection, and save should do it for you.
