The Jelly language was created for Siri Shortcuts because I was not satisfied with the GUI of Shortcuts. I wanted a way to write Shortcuts in a text based language. That is why I created Jellycuts and the Jelly language.
The first place to start is setting up your IDE. The current IDE for Jelly is the Jellycuts iOS App.
Once you have set up your IDE you can head over too Writing Your First Script to learn how to write your first Jellycut script.
