Click the Add New User button on the Users tab in the right part of the screen above the list of users.
Choose between two ways of adding new users in the open window:
In the first case, all you need to do is fill in the online form. This is ideal, if you have only one or several users to add. The second option comes in handy when you have to add a lot of users. In this case, new users are imported into the system from a .CSV file.
