 // This script creates a transport object which can be used to send emails
 
 //  This script requires the following environment variables to be set:
-//  - RELAY_HOST (production)
+//  - DEPLOYMENT_LOCATION : The location where the app is deployed, either local, CSCS or JSC
+//  - EMAIL_HOSTNAME : The hostname of the smtp server, e.g. smtp.gmail.com, a relay server or an ip address.
+//  - EMAIL_ADDRESS_SENDER : The email address of the sender
+//  - EMAIL_PASSWORD : The password of the sender email address (optional, depending on the smtp server configuration)
 
-// In order to use this script locally, you need to create a file called 
-// mail_credentials.js in the same folder as this script. Use the following
-// template for the file: mail_credentials_template.js
-// Make sure to add the file to .gitignore so that you don't commit your
-// credentials to the repository.
