After reading the README twice I still don't know what it does or if I could have any need for it.
What about a more concrete exmaple in the README?
The demo is more speaking. And the tool looks actually interesting.
How about:
With StIGMA you can create a web form GUI from an example JSON object (demo-link).
Example:
x = { "name":"John Smith", "age":24 }; # Make it simple
gets translated to
y = ...
which can be rendered on a webpage as:
[Screenshot]
Then later describe the process in detail.
