 ## Update Azure Boards-GitHub connections
 
 If you change the repositories that the Azure Boards app for GitHub supports, you might get redirected to Azure Boards GitHub connections. A good practice is to remove the repositories in Azure Boards that can no longer connect to GitHub. For more information, see [Add or remove GitHub repositories](#add-remove-repos).
 
 If you uninstall the Azure Boards app for GitHub, the following message displays in Azure Boards, **Project settings** > **GitHub** connections. Choose **Remove connection** to remove all previously made GitHub connections. For more information, see [Add or remove GitHub repositories](#add-remove-repos).
