docs/data/reusables/actions/about-triggers.md

Workflow triggers are events that cause a workflow to run. These events can be:

• Events that occur in your workflow's repository
• Events that occur outside of {% data variables.product.product_name %} and trigger a repository_dispatch event on {% data variables.product.product_name %}
• Scheduled times
• Manual

For example, you can configure your workflow to run when a push is made to the default branch of your repository, when a release is created, or when an issue is opened.
