 ### Using conditionals
 
-You can use conditionals to further control whether jobs or steps in your workflow will run. For example, if you want the workflow to run when a specific label is added to an issue, you can trigger on the `issues labeled` event activity type and use a conditional to check what label triggered the workflow. The following workflow will run when any label is added to an issue in the workflow's repository, but the `run_if_label_matches` job will only execute if the label is named `bug`.

+#### Example using event type
+
+For example, if you want to run different jobs or steps depending on what event triggered the workflow, you can use a conditional to check whether a specific event type exists in the event context. The following workflow will run whenever an issue or pull request is closed. If the workflow ran because an issue was closed, the `github.event` context will contain a value for `issue` but not for `pull_request`. Therefore, the `if_issue` step will run but the `if_pr` step will not run. Conversely, if the workflow ran because a pull request was closed, the `if_pr` step will run but the `if_issue` step will not run.

+```yaml
+on:
+  issues:
+    types:
+      - closed
+  pull_request:
+    types:
+      - closed
