 1. **How to push app updates?**
 
-    Every time you release a new version of your app, you should build, tag and push the new Docker images to Docker Hub. Then open a new PR on our main repo (getumbrel/umbrel) with your up-to-date docker image. For now, app updates will be bundled together in the Umbrel releases. In the future, you'll be able to ship updates independently as soon as you make a new release.

-    Users will install and uninstall the apps via dedicated UI in their dashboard. They will not use the `scripts/app` CLI directly as it's only meant for development use.
