# [Set Up Your Project] - About Stack Users

This page explains what stack users are in Contentstack and the different user types based on permissions. It is intended for developers, admins, and content managers who need to understand user access and roles when setting up and managing a stack.

## About Stack Users

As Contentstack is an Enterprise Content Management (ECM) system, it may have many users with varying permissions working together. All the member accounts of a stack are called users in Contentstack. Depending on the permissions they have, users can be classified into five types:
- Owner
- Admin
- Developer
- Content Manager
- User with custom permissions

**Note:** A user added to a stack can access and perform actions across branches present in the stack as per the roles assigned to them. Refer to our [Global Modules](/docs/developers/branches/global-modules) document for more information.

**Additional Resources:** View [Roles](/docs/developers/invite-users-and-assign-roles/types-of-roles) to learn more about the permissions of each type of users.
