+## App Not Starting After Update to 2.0.4
+
+Version 2.0.4 introduced changes to how the config is read, and the app is build. If you were previously mounting `/public` as a volume, then this will over-write the build app, preventing it from starting. The solution is to just pass in the file(s) / sub-directories that you need. For example:
+
+```yaml
+volumes:
+- /srv/dashy/conf.yml:/app/public/conf.yml
+- /srv/dashy/item-icons:/app/public/item-icons
+```

 ## Keycloak Redirect Error
 
 Check the [browser's console output](#how-to-open-browser-console), if you've not set any headers, you will likely see a CORS error here, which would be the source of the issue.
