What is YAML Syntax?
GitHub Actions workflows are written in YAML, a human-readable format that uses indentation to represent structure instead of brackets or tags. A workflow file defines keys like on for triggers, jobs for the tasks to run, and steps for individual commands within each job. Getting the indentation right is important, since YAML is sensitive to spacing and incorrect indentation can break the entire workflow.
