How to manage the locations of my menu in the ColorLight theme?

Hi,

To create a menu I go to “Appearance” then “Menus”, in the “Menu Name” box write the name for your menu (e.g. “menu1”) and click on “Create Menu”. Then check the page I want under the left column “Pages” and then click on “Add to Menu”, then I click on “Save Menu”.

But how to make this menu appear on my pages, and is possible to manage the locations of my menu?

Thank you,
Vincent
