 ### Verify Deployment
 
-After the deployment completes, we can access the Superset UI .  For demo purpose, this blueprint creates the Ingress object for the Superset FrontEnd UI with public LoadBalancer.
+After the deployment completes, we can access the Superset UI .  For demo purpose, this blueprint creates the Ingress object for the Superset FrontEnd UI with public LoadBalancer and also number of pods across 2 AZ's in the corenode and superset node respectively.

+In order to visualize  data, we need to first connect to  Postgres database. the IP address of the database can be obtained by describing a pod 'superset-postgresql-0'. Basically the database is hosted on the superset-node
+
+
+```sh
+k describe po superset-postgresql-0 -n superset
+
+```
+
+
+After obtaining the IP address, database connection can be established as per the screenshot below

+
+Once the database is connected, it has to be configured to allow file upload. This features allows, csv and other format files to be uploaded as a new table. Please refer to the screeshots below
+
+Step -1 : Edit database configuration and navigate to 'ADVANCED' settings
+

+
+Step - 2 : Under Security scroll down to the very end and 'check allow file uploads to the database'

+Step - 4 : To show a sample visualization a sample CSV of COVID research across various countries was uploaded. Here are a few visualizations that shows countries porgess with respect to trial of various vaccines
