This is an annotated config.yml for a simple Phoenix web application, which you can access at https://github.com/CircleCI-Public/circleci-demo-elixir-phoenix.
If you’re in a rush, just copy the configuration below into .circleci/config.yml in your project’s root directory. Otherwise, we recommend reading through the whole configuration for better understanding.
