+=== "Docker plugins"
+
+    Docker offers plugins on its website (e.g. [Docker Plugins amd64 stable](https://download.docker.com/linux/debian/dists/bookworm/pool/stable/amd64/)), some of them are not installed by the Docker installation by default resp. are no install option from `dietpi-software` (like the Docker Compose plugin is one).  
+    These additional plugins can be installed by the user as described below.
+
+    [Docker Buildx](https://docs.docker.com/build/architecture/) CLI plugin:
+
+    ```sh
+    apt install docker-buildx-plugin
+    ```
+
+    [Docker vulnerability scan](https://docs.docker.com/docker-hub/vulnerability-scanning/) CLI plugin:
+
+    ```sh
+    apt install docker-scan-plugin
+    ```
+
+    For [running container rootless](https://docs.docker.com/engine/security/rootless/):
+
+    ```sh
