# Invite collaborators

To grant other users access to a project, you can add them as collaborators. To add collaborators, you must be a Contributor to the project, or the project Owner.

1. In the Project, go to **Settings** > **Access & Sharing**.

2. In the **Collaborators and permissions** section, enter a username, email address, or organization name.

   If you enter an email address for a Domino user, they will be invited to join the project as a collaborator. If you enter an email address that is not associated with an existing Domino user, they are invited to join Domino.

3. Click **Invite**.

4. Set the **Role** for the collaborator.

   **Contributors**\
   Can read and write project files, and start runs. On the **Settings** page, Contributors can read and write project environment variables, and they can invite new collaborators. Contributors can also change hardware tier and environments.

   **Results Consumers**\
   Can only read files and access [published apps](/cloud/platform-capabilities/core-concepts/products/apps).

   **Launcher Users**\
   Can only view and run Launchers, and see the launcher runs results. They cannot view project files.

   **Project Importers**\
   Can [import the project](/cloud/platform-capabilities/core-concepts/projects/collaborate-on-projects/export-import-project), but otherwise cannot access it.

   **Owners**\
   You cannot select this role as this is the project owner. These are the only users who can archive a project, change the owner, change collaborator types, import or export to share environment variables and files between projects, or set automatic workspace shutdown times.

   See [Collaborator Permissions](/cloud/platform-capabilities/core-concepts/projects/collaborate-on-projects/collaborator-permissions) for specific project permissions for each type of collaborator.

5. In **Notifications preference**, select how to [notify](/cloud/platform-capabilities/core-concepts/jobs/customize-job-results) the collaborator when runs complete. This keeps your collaborators up-to-date about the work that each person is doing.
