Click on User CP on the left of the page, right under the top ad. Then, you will be brought to your Control Panel, where you will have a bunch of tabs on the left to click on. Choose the topmost one, "Edit your details", and then scroll down to the "Additional Information" block, where one of the options is to give your location.
In "Edit my details" and under other tabs in the user CP, you will find pretty much everything you need to set up your profile. You can change your user title (the little blurb of text below your username) and add a few details about yourself in "Edit your details". In other tabs, you can add an avatar, edit your your signature, etc.
Pictures added on bottom to help you find where to do add your location.
