 ## Improve performance with smart deployments
 
+> [!TIP]
+> To ensure smart deployments works in GitHub, Workflows must have read and write permissions on your repositoriy. See [Managing GitHub Actions settings for a repository](https://docs.github.com/en/repositories/managing-your-repositorys-settings-and-features/enabling-features-for-your-repository/managing-github-actions-settings-for-a-repository) for more details.

 The **smart deployments** feature is a back-end capability that improves performance by actively tracking modifications made to the content files of a connected repository. It uses a CSV file within the '.sentinel' folder in your repository to audit each commit. The workflow avoids redeploying content that hasn't been modified since the last deployment. This process improves your deployment performance and prevents tampering with unchanged content in your workspace, such as resetting dynamic schedules of your analytics rules.
 
 Smart deployments are enabled by default on newly created connections. If you prefer all source control content to be deployed every time a deployment is triggered, regardless of whether that content was modified or not, you can modify your workflow to disable smart deployments. For more information, see [Customize the workflow or pipeline](ci-cd-custom-deploy.md#customize-the-workflow-or-pipeline).
