-## FAQ
+Via Kubernetes:
 
-  * ### How do I change the size of the virtual disk?
+```shell
+kubectl apply -f https://raw.githubusercontent.com/vdsm/virtual-dsm/refs/heads/master/kubernetes.yml
+```
 
-    To expand the default size of 16 GB, locate the `DISK_SIZE` setting in your compose file and modify it to your preferred capacity:
+## Compatibility ⚙️
 
-    ```yaml
+| **Product**  | **Platform**   | |
-    environment:
+|---|---|---|
-      DISK_SIZE: "128G"
+| Docker Engine | Linux| ✅ |
-    ```
+| Docker Desktop | Linux | ❌ |
-    
+| Docker Desktop | macOS | ❌ |
-    This can also be used to resize the existing disk to a larger capacity without any data loss. 
+| Docker Desktop | Windows 11 | ✅ |
+| Docker Desktop | Windows 10 | ❌ |
 
-  * ### How do I change the location of the virtual disk?
+## FAQ 💬
 
-    To change the location of the virtual disk, include the following bind mount in your compose file:
+### How do I use it?
 
-    ```yaml
+  Very simple! These are the steps:
-    volumes:
+  
-      - /var/dsm:/storage
+  - Start the container and connect to [port 5000](http://localhost:5000) using your web browser.
-    ```
 
-    Replace the example path `/var/dsm` with the desired storage folder.
+  - Wait until DSM is ready, choose an username and password, and you will be taken to the desktop.
+  
+  Enjoy your brand new NAS, and don't forget to star this repo!

-    sudo kvm-ok
-    ```
 
-    If you receive an error from `kvm-ok` indicating that KVM acceleration can't be used, check the virtualization settings in the BIOS.
+   It is possible to pass-through a disk device directly, by adding it to your compose file in this way:
 
-  * ### How do I assign an individual IP address to the container?
+  ```yaml
+  devices:
+    - /dev/disk/by-uuid/12345-12345-12345-12345-12345:/disk2
+  ```
 
-    By default, the container uses bridge networking, which shares the IP address with the host. 
+  Make sure to bind the disk via its UUID (obtainable via `lsblk -o name,uuid`) instead of its name (`/dev/sdc`), to prevent ever binding the wrong disk when the drive letters happen to change. 
 
-    If you want to assign an individual IP address to the container, you can create a macvlan network as follows:
+> [!IMPORTANT]
+> The device needs to be totally empty (without any partition table) otherwise DSM does not always format it into a volume.
 
-    ```bash
+> [!CAUTION]
-    docker network create -d macvlan \
+> Do NOT use this feature with the goal of sharing files from the host, they will all be lost without warning when DSM creates the volume.
-        --subnet=192.168.0.0/24 \
-        --gateway=192.168.0.1 \
-        --ip-range=192.168.0.100/28 \
-        -o parent=eth0 vdsm
-    ```
-    
-    Be sure to modify these values to match your local subnet. 
 
-    Once you have created the network, change your compose file to look as follows:
+### How do I change the amount of CPU or RAM?
 
-    ```yaml
+  By default, the container will be allowed to use a maximum of 1 CPU core and 1 GB of RAM.
-    services:
-      dsm:
-        container_name: dsm
-        ..<snip>..
-        networks:
-          vdsm:
-            ipv4_address: 192.168.0.100
 
-    networks:
+  If you want to adjust this, you can specify the desired amount using the following environment variables:
-      vdsm:
-        external: true
-    ```
-   
-    An added benefit of this approach is that you won't have to perform any port mapping anymore since all ports will be exposed by default.
 
-    Please note that this IP address won't be accessible from the Docker host due to the design of macvlan, which doesn't permit communication between the two. If this is a concern, you need to create a [second macvlan](https://blog.oddbit.com/post/2018-03-12-using-docker-macvlan-networks/#host-access) as a workaround.
+  ```yaml
+  environment:
+    RAM_SIZE: "4G"
+    CPU_CORES: "4"
+  ```
 
-  * ### How can the container acquire an IP address from my router?
+### How do I verify if my system supports KVM?
 
-    After configuring the container for macvlan (see above), it is possible for DSM to become part of your home network by requesting an IP from your router, just like your other devices.
+  Only Linux and Windows 11 support KVM virtualization, macOS and Windows 10 do not unfortunately.
+  
+  You can run the following commands in Linux to check your system:
 
-    To enable this feature, add the following lines to your compose file:
+  ```bash
+  sudo apt install cpu-checker
+  sudo kvm-ok
+  ```
 
-    ```yaml
+  If you receive an error from `kvm-ok` indicating that KVM cannot be used, please check whether:
-    environment:
-      DHCP: "Y"
-    device_cgroup_rules:
-      - 'c *:* rwm'
-    ```
 
-    Please note that even if you don't want DHCP, it's still recommended to enable this feature as it prevents NAT issues and increases performance by using a `macvtap` interface. In that case just set a static IP from the DSM control panel after you enabled this mode.
+  - the virtualization extensions (`Intel VT-x` or `AMD SVM`) are enabled in your BIOS.
 
-  * ### How do I passthrough the GPU?
+  - you enabled "nested virtualization" if you are running the container inside a virtual machine.
 
-    To passthrough your Intel GPU, add the following lines to your compose file:
+  - you are not using a cloud provider, as most of them do not allow nested virtualization for their VPS's.
 
-    ```yaml
+  If you do not receive any error from `kvm-ok` but the container still complains about KVM, please check whether:
-    environment:
-      GPU: "Y"
-    devices:
-      - /dev/dri
-    ```
 
-    This can be used to enable the facial recognition function in Synology Photos for example.
+  - you are not using "Docker Desktop for Linux" as it does not support KVM, instead make use of Docker Engine directly.
+ 
+  - it could help to add `privileged: true` to your compose file (or `sudo` to your `docker run` command), to rule out any permission issue.
 
-  * ### How do I install a specific version of vDSM?
+### How do I assign an individual IP address to the container?
 
-    By default, version 7.2.1 will be installed, but if you prefer an older version, you can add its download URL to your compose file as follows:
+  By default, the container uses bridge networking, which shares the IP address with the host. 
 
-    ```yaml
+  If you want to assign an individual IP address to the container, you can create a macvlan network as follows:
-    environment:
-      URL: "https://global.synologydownload.com/download/DSM/release/7.0.1/42218/DSM_VirtualDSM_42218.pat"
-    ```
 
-    With this method, it is even possible to switch between different versions while keeping all your file data intact.
+  ```bash
+  docker network create -d macvlan \
+      --subnet=192.168.0.0/24 \
+      --gateway=192.168.0.1 \
+      --ip-range=192.168.0.100/28 \
+      -o parent=eth0 vdsm
+  ```
+  
+  Be sure to modify these values to match your local subnet. 
 
-  * ### What are the differences compared to the standard DSM?
+  Once you have created the network, change your compose file to look as follows:
 
-    There are only two minor differences: the Virtual Machine Manager package is not available, and Surveillance Station will not include any free licenses.
+  ```yaml
-    
+  services:
-  * ### Is this project legal?

+      container_name: dsm
+      ..<snip>..
+      networks:
+        vdsm:
+          ipv4_address: 192.168.0.100
 
-    Yes, this project contains only open-source code and does not distribute any copyrighted material. Neither does it try to circumvent any copyright protection measures. So under all applicable laws, this project would be considered legal.

+      external: true
+  ```
