+### What permissions are needed?
+
+Connecting integrations may require admin-level access depending on your organization's settings:
+
+- **Slack**: Workspace admin permissions to install the Promptless app
+- **GitHub**: Organization admin or sufficient repository access to install the GitHub App
+- **Jira/Confluence**: Atlassian admin permissions to authorize the OAuth connection
+- **Linear**: Workspace admin permissions to connect the integration
+
+Don't have the required permissions? No problem—you can invite teammates during setup.
+
+<Tip>
+If you don't have admin access to connect a particular integration, you can invite someone from your IT or Engineering team directly from the onboarding wizard. The invited person receives an email that brings them to the same onboarding page you're on, and they can pick up exactly where you left off.

Setup doesn't need to be completed by a single person: any teammate you invite can continue from the current step, making it easy to hand off to someone with the right permissions for a specific integration.
