 ## 5. Update connection profile and PostgreSQL credentials
 
-After setting up fabric network and postgreSQL DB as mentioned in step 3 and 4, perform the following steps:
-* replace ```server/config/connection-profile.json``` with your fabric network connection profile which was downloaded in `step 3`.
-* replace ```server/config/local-postgres-config.json``` with your postgreSQL credentials (in case of IBM Cloud PostgreSQL service).
