Hi, I made a small change in the docker awx\_task backend in main/notifications/email\_backend.py. What is the quickest way to have those changes be picked up? Obviously I can restart the docker container, but I’m assuming I can do this with awx\_manage somehow? Many thanks. ---

When developing on AWX it’s best to follow the CONTRIBUTING instructions for the development environment: [https://github.com/ansible/awx/blob/devel/CONTRIBUTING.md](https://github.com/ansible/awx/blob/devel/CONTRIBUTING.md) ---

Thanks Matthew, I have tried following the contribution guide but I am hitting some errors. I have posted a seperate thread about it.
