From your Augmentt homepage, click on System Users in the left hand navigation:
While on the System Users page, click on the New User button located in the upper right hand side of the page:
A dialog box will pop up that you can use to setup a new user. During the setup process you can assign a user the role of Admin or Read-Only. There is not a limit on the number of Admin users that you can have set up in the platform.
You may change the role of an existing user by clicking on the three dots that appear to the right of that user's name in the System Users screen and choosing the Edit option.
After selecting the Edit option a dialog box will appear. The Role field in the dialog box has a drop down arrow on the right hand side that allows you to change the role of the user you are working with. When you are satisfied with your selection, click on the Update button located at the bottom of the dialog box and your changes will take effect.
