Installing the Setster widget on your WordPress blog is fairly straight forward. Copy the Setster Tab Overlay Code from the Get widget section of Setster.

1. Sign into WordPress
2. Under Admin, Go to design.
3. Go the theme editor.
4. On the right sidebar, under Templates, select footer.

Inject code by pasting the copied code between body and html:

</body>
Widget code goes here
</html>

Save your work.

That is it, the appointment widget is now on your blog and you are ready to accept appointments.

If you see this text under that editor box, “ You need to make this file writable before you can save your changes. See the Codex for more information.”

This means that there is extra security on your blog and you will need to edit the file directly with an HTML editor or send it to your web master.

In this case, write it here:

/wp-content/themes/<themename>/footer.php
