Discussion of multi-line strings using literal and folded block scalars, and how to preserve or collapse newlines in YAML.

[1:01:40]
Collections: Maps and Lists
Explanation of YAML collections—maps (key-value pairs) and lists (ordered items), with examples of nested structures like lists of maps.

[1:06:40]
Webhook Trigger for Workflows
Introduction to webhook triggers in GitHub Actions, showing how to set up a workflow that runs on push and pull request events with branch and path filters.

[1:11:40]
Practical Workflow Example
Demonstration of creating a workflow with a test job, including checkout and test steps, and verifying it runs on push and pull request events.

[1:36:09]
Scheduled Triggers and Cron Jobs
Explains scheduled triggers for GitHub Actions, comparing them to Linux cron jobs with five fields (minute, hour, day, month, weekday) and noting UTC timezone usage.

Manual Triggers: Workflow Dispatch
Introduces manual triggers via workflow_dispatch, showing how to run workflows manually from the GitHub UI or CLI with optional inputs like environment selection.

[2:00:00]
Manual Triggers: Repository Dispatch
Covers repository_dispatch triggers for API-only activation, demonstrating how to use curl with a personal access token and event payload to trigger workflows.

[2:12:00]
Jobs and Steps: Parallel vs Sequential
Explains jobs as groups of steps, default parallel execution, and using the 'needs' keyword to enforce sequential order, with a practical example of four jobs.

[2:20:00]
Steps and Multi-Line Scripts
Discusses steps within jobs and using the pipe symbol for multi-line shell scripts in YAML, enabling complex command sequences in a single step.

[2:24:14]
