+## Hot reloading during development
+
+This project uses `spring-boot-devtools` for automatic application restarts
+after code changes.
+
+In IntelliJ IDEA, you can enable hot reloading for the running application with
+the following IDE settings. Note that it can take a few seconds for the refresh
+to happen.
+
+- `Settings` > `Build, Execution, Deployment` > `Compiler`:
+  [X] Build project automatically
+- `Settings` > `Advanced Settings`:
+  [X] Allow auto-make to start even if developed application is currently running
+
+With this configured, you don't need to restart the application manually when
+you made code changes. Hot reload will work both when running the application
+via IntelliJ IDEA from the IDE as well as when running the application in a
+terminal with `./mvnw spring-boot:run`.
+
