 # Configuring Embedded Registry in RKE2
 
 ## Overview
+
 RKE2 allows users to enable an **embedded registry** on control plane nodes. When the `embeddedRegistry` option is set to `true` in the `serverConfig`, users can configure the registry using the `PrivateRegistriesConfig` field.
 The process follows [RKE2 docs](https://docs.rke2.io/install/registry_mirror).
 
 ## Enabling Embedded Registry
+
 To enable the embedded registry, set the `embeddedRegistry` field to `true` in the `serverConfig` section of the `RKE2ControlPlane` configuration:

 ## Configuring Private Registries

 Once the embedded registry is enabled, you can configure private registries using the `PrivateRegistriesConfig` field in `RKE2ConfigSpec`. This field allows you to define registry mirrors, authentication, and TLS settings.

 ## TLS Secret Format

 When configuring the `tlsConfigSecret`, ensure the secret contains the following keys:
+
 - **`ca.crt`** – CA certificate
 - **`tls.key`** – TLS private key
 - **`tls.crt`** – TLS certificate
