The Ember Community Discord is the best place to get in touch.
Once inside Discord, visit the #ec-deploy channel under Ember Addons. A core team member or other community member should be around to help you out.
Our main Github repository is ember-cli-deploy/ember-cli-deploy. Feel free to open an issue if you find a bug or have a technical question.
We have a separate ember-cli-deploy Github org for ember-cli-deploy plugins maintained by the core team.
