Setting up footer contents

Hi I am very new to wordpress. I used to blog in blogspot but now shifted to wordpress. I am having problem to set up footer contents in profitmag theme. Like you can see on my website https://www.sansaryearbook.com, I have not set up footer contents yet, they are same as default. How can I put there my own links and texts? Actually I didnt find anything related to footer in theme option, only header options are given. I know it is a silly question, but you can excuse because I am new!!!
