First, you find a page that has gallery in it. If you want to seperate it to a seperate gallery, make sure it's for a specific reason in before you publish your edit by creating a seperate gallery page. Make sure the gallery is blanked except for
==Gallery==. Then, make sure you copy/type in
==Gallery==. Then the template will show up and says "Click here", upon clicking on "Click here", it will lead you to
(PAGENAMEHERE)/Gallery. Make sure the seperate gallery page is created so the "Click here" will work. You can only make a seperate gallery article of a page if the page has 15 or more than 15 images.
