# Invite collaborators

<mark style="color:$primary;">**Outcome**</mark>\
You invite co-authors and colleagues to your research project with the role that matches their level of involvement.

<mark style="color:$primary;">**Before you start**</mark>

* You are a **Space Administrator** of the project (project creators automatically receive this role).
* You have decided which role each collaborator should hold (Space Administrator vs. Instance Editor - see below).
* You have the email addresses of the collaborators.

Pick the role first, then send the invitation. The two common collaborator patterns:

* **Space Administrator** - gives the collaborator every privilege on the project: editing every instance, inviting more users, creating new instances, and deleting the project. Use for co-authors who need full control.
* **Instance Editor** - limits the collaborator to one specific instance. They cannot create instances, invite users, or modify anything outside that instance. Use for contributors with a defined scope.

For the full role and capability matrix, see [Concepts › Roles, secrets and identity](/concepts/roles-secrets-and-identity.md).

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.nuvolos.com/how-to-guides/workflows-for-researchers/invite-collaborators.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
