# Introduction to metric collections

> Reference documentation for metric collections in Confidence.

Metric collections let you group related metrics together for easier discovery and collaboration.
A collection acts as a curated list of metrics, for example all engagement metrics for a product
launch or the key metrics owned by your team.

Everyone in your organization can view collections. You can control who can
edit a collection through permissions.

## Add and Remove Metrics

On a metric detail page, select **Add to collection** in the page header.
In the dialog, check the collections you want to add the metric to, or clear to remove it.
Click **Save** to apply your changes.

A single metric can belong to multiple collections. Adding a metric to a collection creates a
reference, not a copy.

## Filter by Collection

On the Metrics list page, open the filter bar and select a collection from the **Collection** filter
to show only metrics that belong to that collection.

The collection filter is also available in the metrics picker when adding metrics to an
experiment, helping you quickly narrow down the selection.

## Permissions

The collection owner and admins can manage access by selecting **Permissions**
on the collection page.
