This training is simply about how to change that "free link" in the footer of every page from "proudly powered by WordPress" and linking to WordPress site home page to something of your own choice.
Perhaps "proudly powered by Wealthy Affiliate" with your WA affiliate link behind it is what you want or would be better for you. In my opinion, very well could spark curiosity and interest and earn you a few clicks and possible some commissions.
Apologies for the audio quality.

I would add for anyone new to working with code, it is a good idea to make a copy of the original code by saving it in notepad. If you make a mistake, you will then be able to reverse everything by pasting the original code back. ~Jude
