# Enhance collaboration with fine-grained permissions

Collaboration Permissions is a feature that gives you a fine-grained permission system for defining actions allowed by individual users when multiple users are working on the same document.

Collaboration permissions allow a user to:

- View an annotation or comment.

- Edit an annotation or comment.

- Delete an annotation or comment.

- Reply to a comment thread.

These permissions are based on the configuration present in the [JSON Web Token](https://www.nutrient.io/guides/ios/instant-synchronization/authentication.md) (JWT). Since these permissions can’t be modified on the client side, they’re more secure than the previously existing client-side restrictions.

See the permissions syntax in the [setting user collaboration permissions](https://www.nutrient.io/guides/ios/collaboration-permissions/defining-permissions.md) guide for information on how to configure the permissions from Document Engine.

Collaboration Permissions doesn’t handle the creation of annotations or comments. Such permissions are granted by specifying the `write` permission in the `permissions` array in the JWT.

If Collaboration Permissions is enabled, by default, a user isn’t allowed to perform any of the actions unless specified.

## Licensing

Permissions are available to all users who have [Instant](https://www.nutrient.io/guides/web/instant-synchronization.md) enabled in their license.

## Example

You can use the Collaboration Permissions Example from our [Nutrient Catalog](https://www.nutrient.io/guides/ios/getting-started/example-projects.md#nutrient-catalog) to start a new collaboration session. You can then share the document session link and join as a different user using our examples in a web browser.

Steps:

1. Run the Catalog app and open the Collaboration Permissions Example.

2. Select a user to start the collaboration session as that user.

3. Tap the Collaborate button.

4. Tap Share Document Link.

5. Open the document link in a web browser and you’ll be prompted to opt for the user you’d like to add to the collaboration session.
