# CRM via Helm

> Helm chart installation and version reference for the CRM plugin.

The CRM plugin provides APIs for managing holder data and their relationships with ledger accounts. It includes both a backend and a UI component.

<Note>
  Starting from Midaz chart v5.x, the CRM backend is also available as an integrated workload within the main Midaz chart (enabled via `crm.enabled: true`). The standalone plugin-crm chart remains available for deployments that prefer a separate installation.
</Note>

## Prerequisites

***

* A running Midaz deployment.
* MongoDB instance for CRM data storage.

## OCI registry

***

```bash theme={null}
oci://registry-1.docker.io/lerianstudio/plugin-crm
```

## Installation
