+Since docker manages the dependencies of the container automatically you only need to install docker or podman itself. (Podman is recommended because of the faster container startup times. Note that podman and docker are interchangeable so no instructions will change depending on which one you use)
 
 Note: This will only work on linux systems since some kernel interfaces (like kvm) are needed by the vm. Because of this performance can vary in kernel versions (newer will likely perform better).

+# Setup docker container
+
+The easiest way to setup a windows vm is by using docker compose. Just create a `docker-compose.yml` with following content:
+
+```yaml
+name: "winapps"
+
+volumes:
+  data:
+
+services:
+  windows:
+    image: dockurr/windows
+    container_name: windows
+    environment:
+      VERSION: "win11"
+      RAM_SIZE: "8G"
+      CPU_CORES: "4"
+    privileged:
+true
+    ports:
+      - 8006:8006
+      - 3389:3389/tcp
+      - 3389:3389/udp
+    stop_grace_period: 2m
+    restart: on-failure
+    volumes:
+      - data:/storage
+```
+
+Now you can tune the ram/usage by changing RAM_SIZE/CPU_CORES. You can also specify the windows versions you want to use.
