 This release updates the comment of the dependency updating Pull Request to instruct the user how to trigger the CI build for the Pull Request. It also sends Slack notifications when the dependency check or update fails.
 
+### Migration Guide
+
+When upgrading a repository to the new version make sure that the repository has access to GitHub secret `INTEGRATION_TEAM_SLACK_NOTIFICATION_WEBHOOK`. This is required for Slack notifications for new Pull Requests. The workflows will still run but won't send notifications if the secret is missing.

+## Generated GitHub Workflows
+
+PK generates the following GitHub scheduled Workflows:
+
+### [`broken_links_checker.yml`](../../project-keeper/src/main/resources/templates/.github/workflows/broken_links_checker.yml)
+
+Scheduled weekly, checks Markdown files for broken links.
+
+### [`dependencies_check.yml`](../../project-keeper/src/main/resources/templates/.github/workflows/dependencies_check.yml)
+
+Scheduled daily, checks the Maven project for vulnerable dependencies, creates new issues using [security_issues](https://exasol.github.io/python-toolbox/github_actions/security_issues.html) and starts the [`dependencies_update.yml`](#dependencies_updateyml) workflow that updates dependencies.
+
+### [`dependencies_update.yml`](../../project-keeper/src/main/resources/templates/.github/workflows/dependencies_update.yml)
+
+This workflow is triggered manually or by workflow [`dependencies_check.yml`](#dependencies_checkyml). It updates dependencies, creates a changelog with fixed vulnerabilities and creates a new Pull Requests.
+
+In order to send notifications, this workflow requires GitHub secret `INTEGRATION_TEAM_SLACK_NOTIFICATION_WEBHOOK`.
+
 ## Troubleshooting
 
 **Problem:** Validation on CI fails but succeeds locally. In the CI PK wants to list all dependencies as `Added`.
