 For this reason, spring-boot-devtools disables the caching options by default.
 
 Cache options are usually configured by settings in your `application.properties` file.
+For example, Thymeleaf offers the configprop:spring.thymeleaf.cache[] property.
 Rather than needing to set these properties manually, the `spring-boot-devtools` module automatically applies sensible development-time configuration.
 
 Because you need more information about web requests while developing Spring MVC and Spring WebFlux applications, developer tools suggests you to enable `DEBUG` logging for the `web` logging group.
