The first time you will need to click on "review" link you see on the top, and then on the "tools" tab you see on that page.

The link that you see on the top can be "review" or "tools," depending from the tab you last selected on that page: When you selected the "tools" tab, the link on the top will be "tools" too; when you selected the "review" tab, the link on the top will be "review" too.

Stack Exchange code remembers which tab you selected, and will show the link on the top bar basing on that every time you log in to the site.
