-To change it in the backend, upload it to Buckets/shuffler.appspot.com/generated_apps/baseline.
+# App_sdk
+App_sdk development is continued here: https://github.com/frikky/Shuffle-apps/tree/master/app_sdk
 
-## If you want to update apps.. PS: downloads from docker hub do overrides.. :)
-1. Write your code & check if runtime works
-2. Build app_base image
-3. docker rm $(docker ps -aq) # Remove all stopped containers
-4. Delete the specific app's Docker image (docker rmi frikky/shuffle:...)
-5. Rebuild the Docker image (click load in GUI?)
