# Share By Email

Use the Send Invitation option to invite a collaborator to share a project or run, and to manage collaborator access to shared resources. The shared project or run is visible to the collaborator when they are logged in to their account.

Use this option when you want greater control over who can view your data. For information about using a unique URL that can be used to invite a large group of people, see Share by Link.

When you share a project with a collaborator, the collaborator is granted read-only access to related biosamples, libraries, analyses, and data sets. You can optionally allow write access to the project, which allows collaborators to launch apps that write to the shared project.

When you share a run, related entities are not shared, however the names of entities might be visible in run details.

1. Select a project or run.
2. Select Share, then select Send Invitation.
3. Enter the email address for the collaborator.
4. \[Optional] If you are sharing a run and want to share run data only, clear the Share Associated Project checkbox.
5. Select Add Collaborator.
6. \[Optional] If you are sharing a project, select the access level.
   * Read Only—The collaborator can view data.
   * Write—The collaborator can launch apps that write to the project.
7. Select Save Settings.

# 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 by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://help.connected.illumina.com/basespace/collaborate/share-with-collaborators/share-by-email.md?ask=<question>&goal=<user_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.
