# Permissions | How to add and manage Knowledge Group users and permissions

> Learn how to manage Knowledge Group members: add or remove users by contact, chat, org structure, or bulk import, and assign roles (Owner, Admin, Member, Read-only) for granular permission control.

After you create a Knowledge Group, manage its users. Using a blank group as an example, you can add or remove users, and set user types that correspond to different permissions.

## How to add or remove users

* Add users: Go to the user management list of the group and click **Add user** in the upper-left corner. You can add users via four methods: **Contacts, Group Chat, organizational structure, or bulk import**. Currently, only users within the organization can be added. External users cannot be added.

* Remove users: For users already added to the group, click **Hide chat** under Action to remove the user from the group.

## Knowledge Group role permissions

The roles in a Knowledge Group include: Owner, Admin, User, Read-only user (with download), and Read-only user. The corresponding permissions are as follows:

| Role                           | Group permissions                                                          |
| ------------------------------ | -------------------------------------------------------------------------- |
| Owner                          | Transfer the group, manage the group, edit the homepage and Knowledge Base |
| Admin                          | Manage the group, edit the homepage and Knowledge Base                     |
| User                           | Edit content                                                               |
| Read-only user (with download) | View and download content                                                  |
| Read-only user                 | View only, no download                                                     |

## Knowledge Bases inherit group users by default

Knowledge Bases within a group inherit the group's user permissions by default. To configure permissions separately for a Knowledge Base within a group, go to **Users and permissions** in the Knowledge Base.
