Hi @mahirpiy,

It would be great if you could share how you are using it.

@reuvenharrison thank you!!

my team uses the install script in our CI runner to detect any changes made to our api contracts. we use the generated diff to send a message in an api-changes slack channel, so our client engineers are aware of changes. its part of a bigger api-compatibility overhaul that has our mobile engineers creating data classes directly from the open api yaml. thanks for all you do!
