 ### Using Docker
 
-#### Configure Docker to access the NGINX Instance Manager public registry
-
-{{< include "nim/docker/docker-registry-login.md" >}}
-
-#### Pull the NGINX Instance Manager images
-You can now pull the necessary images for NGINX Instance Manager from the private registry at `private-registry.nginx.com`.
-
-Replace `<version-tag>` with the specific version you want to use.
-
-{{< note >}} The `latest` tag is not supported. {{< /note >}}
-
-```shell
-docker pull private-registry.nginx.com/nms/apigw:<version-tag>
-docker pull private-registry.nginx.com/nms/core:<version-tag>
-docker pull private-registry.nginx.com/nms/dpm:<version-tag>
-docker pull private-registry.nginx.com/nms/ingestion:<version-tag>
-docker pull private-registry.nginx.com/nms/integrations:<version-tag>
-docker pull private-registry.nginx.com/nms/utility:<version-tag>
-```
-
-If needed, you can push these images to your own private registry.
-
-#### Push images to your private registry
-
-After pulling the images, tag them and upload them to your private registry.
-
-1. Log in to your private registry:
-
-   ```shell
-   docker login <my-docker-registry>
-   ```
-
-2. Tag and push each image. Replace `<my-docker-registry>` with your registry’s path and `<version-tag>` with the version you’re using (for example, `2.17.0`):
-
-   - For the `apigw` image:
-
-     ```shell
-     docker tag private-registry.nginx.com/nms/apigw:<version-tag> <my-docker-registry>/nms/apigw:<version-tag>
-     docker push <my-docker-registry>/nms/apigw:<version-tag>
-     ```
-
-   - For the `core` image:
-
-     ```shell
-     docker tag private-registry.nginx.com/nms/core:<version-tag> <my-docker-registry>/nms/core:<version-tag>
-     docker push <my-docker-registry>/nms/core:<version-tag>
-     ```
-
-   - For the `dpm` image:
-
-     ```shell
-     docker tag private-registry.nginx.com/nms/dpm:<version-tag> <my-docker-registry>/nms/dpm:<version-tag>
-     docker push <my-docker-registry>/nms/dpm:<version-tag>
-     ```
-
-   - For the `ingestion` image:
-
-     ```shell
-     docker tag private-registry.nginx.com/nms/ingestion:<version-tag> <my-docker-registry>/nms/ingestion:<version-tag>
-     docker push <my-docker-registry>/nms/ingestion:<version-tag>
-     ```
-
-   - For the `integrations` image:
-
-     ```shell
-     docker tag private-registry.nginx.com/nms/integrations:<version-tag> <my-docker-registry>/nms/integrations:<version-tag>
-     docker push <my-docker-registry>/nms/integrations:<version-tag>
-     ```
-
-   - For the `utility` image:
-
-     ```shell
-     docker tag private-registry.nginx.com/nms/utility:<version-tag> <my-docker-registry>/nms/utility:<version-tag>
-     docker push <my-docker-registry>/nms/utility:<version-tag>

 ### Using Helm with a JWT token
 
-If you don't need a private registry, you can use a JWT token as a Docker configuration secret with Helm charts.
+You can use your NGINX JWT as a Docker configuration secret with Helm charts.
 
 Create a Docker registry secret on the cluster, using the JWT token as the username and `none` as the password. The Docker server is `private-registry.nginx.com`.

 1. Create a `values.yaml` file similar to this example:
 
-    - Replace `<my-docker-registry:port>` with your private Docker registry and port (if needed).
     - In the `imagePullSecrets` section, add the credentials for your private Docker registry.
+    - Change the version tag to the version of NGINX Instance Manager you would like to install. See "Install the chart" below for versions.
