+== Running with AOT optimizations
+
+AOT is a mandatory step to transform a Spring application to a native executable, so it
+is automatically enabled when running in this mode. It is possible to use those optimizations
+on the JVM by setting the `spring.aot.enabled` System property to `true`.
+
+NOTE: When AOT optimizations are included, some decisions that have been taken at build-time
+are hard-coded in the application setup. For instance, profiles that have been enabled at
+build-time are automatically enabled at runtime as well.
