Here you will see "Appearance" in the left sidebar (1). Click on that and other options will open.
Each installed theme is represented by a thumbnail image, which gives some idea of what it might look like. Scroll down to see all of the available themes.
Each theme has a thumbnail image (1), and the name of the theme (2). To really see what the theme looks like, click on "Preview" (3).
If this is the theme that you would like for your website, then click on "Activate" (1). Don't worry if you decide later that this theme is not for you, just repeat these steps to choose a different theme.
