+Run the AIRAPIs.go file using Go.
+
+Prerequisites
+1. Atleast a couple of NBU master servers.
+2. MSDP or CC storage server created on one of them. (Use the nbmaster as the other master server for the script execution)
+3. Trust relationship established between the two NBU masters.
+
+Run cli in AIRAPIs directory
+Go run AIRAPIs.go -nbmaster <master server name> -username <username> -password <passwd>
+
+The script can also create new MSDP storage server (with creds as a/a) depending on user inputs.
+Further lists the replication candidates based on the no of trusted master servers and storage server (MSDP and CC) on them.
+User need to select one of the replication candidate to create AIR relationship on the earlier created MSDP/CC sts or existing one.
+User can delete any existing AIR relationship as well.
