How to edit Rasa Core files?

I have a question. Is it possible to edit Rasa files? I need to make changes to file in rasa/core/channels folder. My Rasa version is currently 2.8.1, installed through pip. Thanks!

Yes, you can fork the repo and make the changes you require. There’s a readme on contributing here.

Once you’ve modified the twilio channel, you can build your own image (preferred) or mount the custom channel into your container.
