# Users

## Overview

The creator of an appRules project database (Admin) is given full access to the project database.  All other users must be added to the user list.

## Maintaining Project Database Users

To add, change, or delete users from your project database list, select Users from the appRules Home Page:

You can add and change users as required.  Once added, users can also change their Startup Project and Designer Settings.

NB: a user is associated to a specific [RuntimeSettings](https://docs.appstrategy.com/apprules-r-documentation/platform/platform-features/system-settings/runtime-settings) value that determines the environment in which the projects will be run (example: Test, Production, PreProd....)
