First of all, thanks for taking the time to contribute!
Ivann is currently maintained by seven Imperial College London students. We will work hard to keep Ivann alive and will try to address issues and PRs as quickly as we can.
If using ivann you have found a bug, or something else that you expected to behave otherwise, please create an issue. Please describe in as much detail as you can the behaviour you came across, and the behaviour you expected instead.
If you have an idea of something that is within the scope of what ivann tries to achieve, we would be happy to hear about it. To let us know please create an issue describing your idea in detail.
If we agree that it would bring value, we will develop it when we can. Alternatively you can make a pull request where you implement your idea yourself, and we will be happy to review it.
In order to get a bug fixed or bring a new feature, you can start your own pull request. If you've never done this, you can find some info here.
