To see all the roles, click on the 'cog' icon and choose 'Roles'. On the 'Environments roles' page you can see the standard roles provided by Artifakt. Click 'View role' to see further details about each of them.
To create a role, click on 'Create role' in the bottom right corner. Type a name for the role and enable the relevant fields for the rights you want to give.
To save time, you can load / copy a role from the menu in the top right corner. It will then automatically enable the associated boxes.
