 # Tutorial: Use dynamic configuration in a Gin web app
 
-This tutorial shows how you can implement dynamic configuration updates in a Gin web application using Azure App Configuration. It builds on the web app introduced in the previous quickstart. Before you continue, complete [Create a Gin web app with Azure App Configuration](./quickstart-go-web-app.md) first.

-In this quickstart, you'll learn how to:
-
-> [!div class="checklist"]
-> * Set up your Gin app to update its configuration in response to changes in an App Configuration store
-> * Implement a middleware to refresh configuration on incoming requests
-> * Inject the latest configuration into your app.

 ## Reload data from App Configuration
 
-1. Open the file *`appconfig.go`*. Inside the `loadAzureAppConfiguration` function, update the `options` to enable refresh. Go provider will reload the entire configuration whenever it detects a change in any of the selected key-values (those starting with *Config.* and having no label). For more information about monitoring configuration changes, see [Best practices for configuration refresh](./howto-best-practices.md#configuration-refresh).
