+## Workflow notifications in Slack
+
+Connect Slack to receive notifications when a workflow runs, completes, or needs your attention. Use this when you want updates to land directly in a channel instead of checking the dashboard.
+
+Slack notifications are configured per project. Each project picks which Slack workspace to install into and which channels receive notifications.
+
+<Note>
+  Notifications use a dedicated Slack app for workflow events. Installing it is separate from connecting the [Mintlify agent to Slack](/agent/slack).
+</Note>
+
+### Connect Slack
+
+1. Open the [Workflows](https://dashboard.mintlify.com/products/workflows?tab=workflows) page in your dashboard.
+2. Start the workflows onboarding flow and continue to the **Workflow notifications** step, or open notification settings from an existing workflow.
+3. Click **Connect slack**, then follow the Slack prompts to install the Mintlify notifications app and grant the requested permissions.
+4. After Slack confirms the install, the channel picker opens automatically so you can select where notifications are delivered.
+
+### Select notification channels
+
+1. In the channel picker, search for the channels you want to receive workflow notifications.
+2. Select one or more channels, then click **Save**.
+3. To change channels later, click **Configure** beside the connected Slack workspace.
+
+Mintlify posts a notification to every selected channel when a workflow run starts, finishes, or fails.
+
+### Skip notifications setup
+
+You can skip Slack setup during onboarding and connect it later from the workflow configuration. Workflows still run on their normal triggers without notifications.

 When a run completes, the run detail in your dashboard includes the specific feedback citations the agent used. Each citation links to the feedback in your [analytics dashboard](https://dashboard.mintlify.com/products/analytics/v2/feedback) so you can verify the context that drove the update.
 
 This workflow runs on a schedule and requires that feedback collection is enabled on the [Add-ons](https://dashboard.mintlify.com/products/addons) page. It does not require trigger repositories or extra context configuration.
