YAML

As explained in .NET MAUI in Action

YAML is a human-readable data serialization format that represents structured data through indentation, whitespace, and key-value syntax.

YAML is a human-readable text format for serializing structured data. Indentation represents hierarchy, making configuration files easy to read and maintain. section 12.2.1 section 12.4

A GitHub Actions workflow uses YAML to define:

  • A workflow name. section 12.2.1
  • Triggers, such as a push to the main branch or a manual workflow dispatch. section 12.2.1
  • Jobs, which contain steps implemented as shell commands or predefined actions. section 12.4
  • GitHub-hosted or self-hosted runners on which jobs execute. section 12.4

Explains indentation, workflow hierarchy, triggers, jobs, steps, and runners through a small configuration example.
Examples
Uses a build-and-deploy.yaml file that triggers on pushes to main or manual dispatch.
What it assumes
Assumes only familiarity with text files while introducing YAML structure through a GitHub Actions example.
What you can do after
Builds a basic GitHub Actions workflow file with a name and execution triggers.
How it connects
Connects YAML with GitHub Actions, CI/CD pipelines, triggers, jobs, steps, and runners.
