# Let's Get Labeling!

Labeling projects fall under three broad categories: **span-based**, **row-based**, and **document-based**.

## Project settings

If you have already created a project, you can change the configurations through **Settings**.

You can click the **File** menu and choose **Settings**.

### Span-based projects

* **Personalization** tab allows you to adjust the font type and font size, show index bar for labels, and configure labeling behavior. This tab is available to labelers and reviewers.

### Document-based projects

Document-based projects have similar settings to row-based projects. The difference is the **Auto mark document as complete** toggle in the **Administrator** tab.

## Roles

Datasaur has 5 team roles. You can manage members' roles in the **Members** page.

### Admin

You automatically become an admin when you create a team. You can create projects, invite members, assign them as labelers or reviewers, and promote them to admins. You can access all of your team's projects and progress.

### Team reviewer

Reviewers role can be assigned at the team or project level. As a team reviewer, you can access and review all projects in the team.

### Project reviewer

Project reviewers are assigned in step 4 during project creation. If their workspace role is labelers, they can only access and review the projects assigned to them.

### **Labeler**

Labeler is the default role when an admin invites someone to a team. As a labeler, you can only see the projects assigned to you.

### **Labeler + reviewer**

If you are a team admin, you can assign yourself as a labeler to a project. Since admins can oversee all projects, you are automatically assigned the **Labeler + reviewer** role when you assign yourself in step 4 of project creation.
