+## User Customization
+
+Add-ons support end-user customization without rebuilding the image (see the repo wiki). At startup, `99-custom_script.sh` looks in the add-on's config directory for a user-provided `script.sh` (seeded from `.templates/script.template`) and executes it. Combined with the `env_vars` passthrough and the custom-script modules, this lets users inject commands and environment without forking the add-on.
