How to Publish First App on FlatHub?

Hi.
I would like to publish my application in Python GTK on FlatHub, but I don’t know how. What should be in com.mydomain.app.json (sample example)? And is there supposed to be anything else to publish than just the json file? Can you help me? Thank you in advance for your help.

I think you should first read the documentation and follow the process. I was in your situation recently and found out all is very well documented.
