Robot.js example

I am trying to understand the new SDK feature in the 20.2 update.

Can anyone provide a sample process and sample of where the js is implemented for me to run and see for myself.

Also is there any thing i must set up in the studio or robot before beginning?

Check out the boilerplate sample on: https://robotjs.uipath.com/samples
If you install community 20.2 or later you should have the Add-on by default.
