 ### Events
 
-An event is a specific activity in a repository that triggers a workflow run. For example, activity can originate from {% data variables.product.prodname_dotcom %} when someone creates a pull request, opens an issue, or pushes a commit to a repository.  You can also trigger a workflow to run on a schedule, by [posting to a REST API](/rest/repos#create-a-repository-dispatch-event), or manually.
