Getting Started with porter.yaml

Writing a porter.yaml for your app is a great way to maintain a single source of truth on how your app should be built and deployed. Though this file is not required, it can reduce the time it takes to get started with a Porter app. Once you start creating your app in Porter and select a Github repository, Porter will automatically read your porter.yaml to prepopulate settings for your app’s services.

​
