Add screenshot or gif in readme to demonstrate integration in action

This might reduce the friction and have people go forward with integrating it with their project. Or maybe just a link to the pull-requests to see it in action? Could be interesting to pin point a specific case where it was actually helpful :)

Might be interesting to mention caveats as well 😅 but I assume anyone using GPT already knows about this by now.

Thanks for trying Reviewer! <3

Definitely need to filter the messages where GPT is basically only responding with "my training data" and "cutoff" or "not connected to internet".

Great suggestion. Indeed, I'm looking to make a video / gif for the readme as well, hopefully once it's able to respond with 3 simple points and not the cutoff or not-connected message. Happy to accept a preliminary one for now if you have any nice ideas.
