# What are teams & users?

Teams and users describe **ownership** in EventCatalog.

You can assign ownership to any resource in EventCatalog.

Teams & users can be manually created or you can [sync them with your existing systems](/docs/development/guides/owners/automated-teams-and-users.md).

## Teams[​](#teams "Direct link to Teams")

A team is a group of users. Teams are useful when ownership belongs to a platform team, product team, domain team, or operating group rather than one person.

Teams live in the `/teams` folder and can reference users in their frontmatter.

## Users[​](#users "Direct link to Users")

A user represents a person in your organization. Users are useful when a specific person owns, maintains, or can answer questions about a resource.

Users live in the `/users` folder and can be assigned directly as owners or added to teams.

## How ownership works[​](#how-ownership-works "Direct link to How ownership works")

You can assign teams and users to resources using owner fields in resource frontmatter.

For example, a domain, service, message, or agent can reference a team or user id in its `owners` array. EventCatalog then shows that ownership on the resource page and links back to the team or user.
