A quick walkthrough of the updated Chrome Extension and its functionality:
Add the genei Chrome Extension to your tools from the Chrome Web Store (link, here)
Go to the desired page or article that you want summarised, and click the extension logo [as seen in the image below - next to other extension icons]
Once clicked, the genei extension will pop-up in the top right-hand of your screen.
This should contain the desired summary for your chosen page [see below].
