 ## How to start
 
 __Step 1.__ Prepare ENV variables.
 
     /* FTP storage for database dumps. */
-    BACKUP_FTP_HOST=yourftp.example.com
-    BACKUP_FTP_USER=user
-    BACKUP_FTP_PASSWORD=password
+    PG_EXPORT_GATEWAY_HOST=yourftp.example.com
+    PG_EXPORT_GATEWAY_USER=user
+    PG_EXPORT_GATEWAY_PASSWORD=password
     
     /* Encryption key shoul have exactly 16 characters. */
     /* Dumps will be SSL(AES-128-CBC) encrypted using this key. */
-    DUMP_ENCRYPTION_KEY=1234567890abcdef
+    PG_EXPORT_ENCRYPTION_KEY=1234567890abcdef
     
     /* Dumps to be kept on FTP */
     /* Optional, defaults to 10 */
     KEEP_DUMPS=5
     
 Note, that variables cannot include `#` sign, [more info](http://serverfault.com/questions/539730/environment-variable-in-etc-environment-with-pound-hash-sign-in-the-value). 
 
 __Step 2.__ Print the configuration to verify if env variables has been loaded properly.
 
     $ pg_export --configuration
-    => {:dump_encryption_key=>"k4***", :ftp_host=>"yourftp.example.com", :ftp_user=>"your_ftp_user", 
-       :ftp_password=>"pass***", :logger_format=>"plain", :keep_dumps=>2} 
+    => {:dump_encryption_key=>"k4***", :gateway_host=>"yourftp.example.com", :gateway_user=>"your_gateway_user",
+       :gateway_password=>"pass***", :logger_format=>"plain", :keep_dumps=>2}
        
 __Step 3.__ Try connecting to FTP to verify the connection.
 
-    $ pg_export --ftp
+    $ pg_export --gateway ftp --welcome
     => 230 User your_ftp_user logged in
     
 __Step 4.__ Perform database export.
 
     $ pg_export -d your_database [-k 5]
