How do I add a read more tag to the slider

Hi

Hope all is good! It's nice to be part of this community. I am currently working on this site http://www.srinivasarka.org/. I was wondering how I go about adding a Read More tag or something similar to the slider next to the title. I know the theme is not part of wpmu, but I would be grateful if you can help me, this would be greatly appreciated. Thanks
