+# Email template customization.
+
+_Introduced in [v4.8.0](https://github.com/InseeFrLab/keycloakify/releases/tag/v4.8.0)_
+
+It is now possible to customize the emails sent to your users to confirm their email address ect.  
+Just run `npx create-keycloak-theme-email-directory`, it will create a `keycloak_theme_email` directory
+at the root of your project.  
+This directory should be tracked by Git (`yarn add -A`)
+You can start hacking the default template.  
+When `npx build-keycloak-theme` (`yarn keycloak`) is run. If the directory `keycloak_theme_email` exists
+at the root of your project, it will be bundled into your `.jar` file and you will be able to select
+it [in the Keycloak administration pages](https://user-images.githubusercontent.com/6702424/164299589-75f8008b-b24e-4836-ad6b-72149bb55621.png).
