# CRM via Helm

> Helm chart installation and version compatibility reference for deploying the CRM plugin on Kubernetes alongside Midaz and other Lerian products.

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
