# Workflow concepts
Concept and reference material for the components that make up a workflow definition. Use this section when you need to know what a specific trigger or step accepts, what its output looks like, or how templating expressions are evaluated.
- [Triggers](https://www.elastic.co/elastic/docs-builder/docs/3276/explore-analyze/workflows/triggers): Manual, scheduled, alert, and event-driven triggers.
- [Steps](https://www.elastic.co/elastic/docs-builder/docs/3276/explore-analyze/workflows/steps): Action, flow control, AI, data, and composition steps.
- [Templating engine](https://www.elastic.co/elastic/docs-builder/docs/3276/explore-analyze/workflows/templating): Liquid templating syntax and custom filters.
- [Reference](https://www.elastic.co/elastic/docs-builder/docs/3276/explore-analyze/workflows/reference): Quick-reference pages for the workflow YAML surface. Cheat sheet, A-Z step type index, context variables, and the Liquid filter catalog.
