# Sharing
The Sharing tab allows you to share your database service with other Tessell users and manage their access roles.
***
## How do I share a database service with another user?
Two roles are available:
| Role | Access level |
| ------------- | -------------------------------------------------- |
| **Co-owner** | Can perform most management actions on the service |
| **Read-only** | Can view service details but cannot make changes |
> **Note:** Only users with **Data Owner** roles in your Tessell account appear in the user dropdown. Users and roles are managed in the [IAM application](/tessell/app-families/governance/iam.md) under the **Governance** app family.
### Steps to share a service
1. Click **Share** (top-right of the Sharing tab).
2. Choose a **Role** from the dropdown (Co-owner or Read-only).
3. Select one or more users from the users dropdown.
4. Click **Share**.
***
## How do I change a user's role or remove their access?
The sharing table shows all users the service is shared with, and their current role. Use the **search bar** to find a specific user.
Click the ellipsis icon next to a user entry for the following options:
### Change Role
1. Click **Change Role**.
2. Select the new role (Co-owner or Read-only) from the dropdown.
3. Click **Update**.
### Remove User
1. Click **Remove User**.
2. Confirm the removal in the dialog.
3. Click **Remove**.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://docs.tessell.com/tessell/database-engines/tessell-for-postgresql/db-services/readme-postgresql/homepage-postgresql/sharing-postgresql.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
