Key fields

Field	Purpose
schema_version	Config format version.
organization	Ownership scope. In solo examples this can be solo.
project	Application/project name.
default_environment	Environment selected when no override is provided.
build	Docker build context, Dockerfile, and target platforms.
services	Named runtime units. Each HTTP service needs ports and a health check.
tasks.release	Optional one-shot release command.
ingress	Hostnames, route rules, TLS behavior, and HTTP redirects.
environments	Per-environment overlays.

Services are explicit. Do not rely on fixed concepts such as one web and one worker; name the runtime units your app actually needs.
