First thing to do in the Users is to set up an admin Users for the Lab itself. There should only be 1 or 2 admin users, these users should be personel working for the lab, preferably Lab Managers. These Admin users will be responsible to add regular users (Doctors/ECP). They will have to add their account in Rx-Universe as a Customer and then link the account in the account link below.
This Tab would be used by the Lab Manager to add a new users (ECP). This is where they would create the users login information and password. Also would need to match the "Account" to the same "Account" of Rx-Universe for this particular ECP.
