+<Info>
+  The Slack app is available for [Pro and Enterprise plans](https://mintlify.com/pricing?ref=slack-app).
+</Info>
+
+The Slack app adds a bot to your Slack workspace that searches your documentation to answer users' questions. The bot responds to direct messages, @mentions, and to any questions in a channel specifically named `#ask-ai`.
+
+## Setting up the Slack app
+
+<Note>
+  If your Slack Workspace Owner requires admin approval to install apps, ask them to approve the Mintlify Slack app before you add it.
+</Note>
+
+1. Navigate to the [Integrations](https://dashboard.mintlify.com/settings/organization/integrations) page of your dashboard.
+2. Select **Connect** in the Slack integration card.
+3. Follow the Slack prompts to add the app to your workspace.
+4. Test that the bot is working and responds when you:
+  - Send a direct message to the Mintlify app.
+  - Mention the bot with `@mintlify` in a channel.
+  - Create an `#ask-ai` channel, add the bot, and ask a question.
