Sharing how I resolved this since not a lot of people touched on what to do if you cant see the "About" gear icon to update the description. So I had to upload a file into my repo and then the About section was visible and I could update my description. So....how do you upload a file? :) When you're in the repo in question, click on the Code tab if you're not already there. On that screen there is a section that says to upload a file or create a new one. Click on that link and follow the instructions to upload a file. I just created a random blank txt file and uploaded that and that was good enough. As soon as I did that, the About section was visible and I was able to update my description. Yes, an necessary set of steps to perform just to update a description, but I'm sure someone smarter than myself has a really good reason for it.
