Is there a link, video or some other basic step by step installation instructions for Q&A

Is there a link, video or some other basic step by step installation instructions?

I did visit https://premium.wpmudev.org/project/qa-wordpress-questions-and-answers-plugin/#usage and after Step 2; I get lost on how or where exactly to continue the installations process. Step by step instructions with pictures, verbiage, or videos would be helpful because there seems to be a few things missing.
