# Launch Datahub

> Launch DataHub to create tags and explore data lineage.

You can create new tags on DataHub or perform additional features,
such as tracing data lineage.

## Prerequisite

Appropriate permission: `datahub-admin`

<Info>All users have read access to DataHub without the `datahub-admin` role.
However, creating, or deleting resources such as a Domain requires write access
via the `datahub-admin` role.</Info>

## Launch DataHub

Perform these steps to launch DataHub.

1. Log in to NexusOne.
2. On the top navigation bar, hover your mouse over **Catalog & Models** and then select **Data Catalog**.

This opens the DataHub app hosted on NexusOne in a new tab.
