# Schemas

{% hint style="success" %}
For automation use the [`CLI`](/latest/devx/5.5/user-guide/cli.md).

To delete schemas you need to enable **`lenses.schema.registry.delete`** in `lenses.conf`.

To connect your Schema Registry see [provisioning](/latest/devx/5.5/deployment/installation/automation/file-watcher-provisioning.md).
