I wrote this guide because every other article out there either asks you to charge the Ring Video Doorbell and mount it OR use an indoor power adapter. This article mentions the components and settings required to hardwire the doorbell and use it with a doorbell transformer and Ring Chime. This way your Ring video doorbell gets trickle charged and you do not need to bother with charging the batteries often or buying additional battery for uninterrupted usage.
This article is specific to Ring Video Doorbell 2 and Ring Video Doorbell 3 ONLY and if your doorbell transformer is integrated in your existing doorbell. This article shows the work I had done myself and is for reference only - I accept no liability for injury, loss or damage due to this article. Connecting the Ring Video Doorbell to an AC transformer requires some knowledge of wiring and soldering. Please consult an electrician for assistance.
Hardwired vs. Battery Powered Operation
The rechargeable battery that comes included with your Ring Video Doorbell can power your device without being connected to an external power source. However, it will need to be recharged on a regular basis. On the other hand, a hardwired Ring Video Doorbell uses the trickle charge it gets solely to charge the battery.
So even though its hardwired, the Ring Video Doorbell still requires that a battery be inserted. This is because it does not actually use the wired power to run its operations but instead relies on the battery for that. Personally, I think this is better as the Ring Video Doorbell 2 or 3 will be able to function off the battery power in the event of a power failure unlike the Ring Video Doorbell Pro.

And this is how the final set up looks like:
