-  * ### 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:
+##### Via Github Codespaces:
 
-    ```yaml
-    environment:
-        DISK_SIZE: "256G"
-    ```
+[![Open in GitHub Codespaces](https://github.com/codespaces/badge.svg)](https://codespaces.new/vdsm/virtual-dsm)
 
-  * ### How do I change the location of the virtual disk?
+## FAQ 💬
 
-    To change the virtual disk's location from the default Docker volume, include the following bind mount in your compose file:
+### How do I use it?
 
-    ```yaml
-    volumes:
-        - /home/user/data:/storage
-    ```
+  Very simple! These are the steps:
+  
+  - Start the container and connect to [port 5000](http://127.0.0.1:5000/) using your web browser.
 
-    Replace the example path `/home/user/data` with the desired storage folder.
+  - Wait until DSM finishes its installation
+ 
+  - 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!
 
-  * ### How do I change the space reserved by the virtual disk? 
+### How do I change the storage location?
 
-    By default, the entire disk space is reserved in advance. To create a growable disk that only reserves the space that is actually used, add the following environment variable:
+  To change the storage location, include the following bind mount in your compose file:
 
-    ```yaml
-    environment:
-        ALLOCATE: "N"
-    ```
+  ```yaml
+  volumes:
+    - ./dsm:/storage
+  ```
 
-    Keep in mind that this will not affect any of your existing disks, it only applies to newly created disks.
+  Replace the example path `./dsm` with the desired storage folder or named volume.
+ 
+### How do I change the size of the disk?
 
-  * ### How do I increase the amount of CPU or RAM?
+  To expand the default size of 16 GB, locate the `DISK_SIZE` setting in your compose file and modify it to your preferred capacity:
 
-    By default, a single core and 512 MB of RAM are allocated to the container. To increase this, add the following environment variables:
+  ```yaml
+  environment:
+    DISK_SIZE: "128G"
+  ```
+  
+> [!TIP]
+> This can also be used to resize the existing disk to a larger capacity without any data loss.
 
-    ```yaml
-    environment:
-        CPU_CORES: "4"
-        RAM_SIZE: "2048M"
-    ```
+### How do I create a growable disk?
 
-  * ### How do I verify if my system supports KVM?
+  By default, the entire capacity of the disk will be reserved in advance.
 
-    To verify if your system supports KVM, run the following commands:
+  To create a growable disk that only allocates space that is actually used, add the following environment variable:
 
-    ```bash
-    sudo apt install cpu-checker
-    sudo kvm-ok
-    ```
+  ```yaml
+  environment:
+    DISK_FMT: "qcow2"
+  ```
 
-    If you receive an error from `kvm-ok` indicating that KVM acceleration can't be used, check your BIOS settings.
+### How do I add multiple disks?
 
-  * ### How do I assign an individual IP address to the container?
+  To create additional disks, modify your compose file like this:
+  
+  ```yaml
+  environment:
+    DISK2_SIZE: "32G"
+    DISK3_SIZE: "64G"
+  volumes:
+    - ./example2:/storage2
+    - ./example3:/storage3
+  ```
 
-    By default, the container uses bridge networking, which shares the IP address with the host. 
+### How do I pass-through a disk?
 
-    If you want to assign an individual IP address to the container, you can create a macvlan network as follows:
+   It is possible to pass-through disk devices or partitions directly by adding them to your compose file in this way:
 
-    ```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. 
+  ```yaml
+  devices:
+    - /dev/sdb:/disk1
+    - /dev/sdc1:/disk2
+  ```
 
-    Once you have created the network, change your compose file to look as follows:
+  Make sure it is totally empty (without any filesystem), otherwise DSM may not format it as a volume.
 
-    ```yaml
-    services:
-        dsm:
-            container_name: dsm
-            ..<snip>..
-            networks:
-                vdsm:             
-                    ipv4_address: 192.168.0.100
+### How do I change the amount of CPU or RAM?
 
-    networks:
+  By default, the container will be allowed to use a maximum of 2 CPU cores and 2 GB of RAM.
+
+  If you want to adjust this, you can specify the desired amount using the following environment variables:
+
+  ```yaml
+  environment:
+    RAM_SIZE: "4G"
+    CPU_CORES: "4"
+  ```
+
+### How do I verify if my system supports KVM?
+
+  First check if your software is compatible using this chart:
+
+  | **Product**  | **Linux** | **Win11** | **Win10** | **macOS** |
+  |---|---|---|---|---|
+  | Docker CLI        | ✅   | ✅       | ❌        | ❌ |
+  | Docker Desktop    | ❌   | ✅       | ❌        | ❌ | 
+  | Podman CLI        | ✅   | ✅       | ❌        | ❌ | 
+  | Podman Desktop    | ✅   | ✅       | ❌        | ❌ | 
+
+  After that you can run the following commands in Linux to check your system:
+
+  ```bash
+  sudo apt install cpu-checker
+  sudo kvm-ok
+  ```
+
+  If you receive an error from `kvm-ok` indicating that KVM cannot be used, please check whether:
+
+  - the virtualization extensions (`Intel VT-x` or `AMD SVM`) are enabled in your BIOS.
+
+  - you enabled "nested virtualization" if you are running the container inside a virtual machine.
+
+  - you are not using a cloud provider, as most of them do not allow nested virtualization for their VPS's.
+
+  If you did not receive any error from `kvm-ok` but the container still complains about a missing KVM device, it could help to add `privileged: true` to your compose file (or `sudo` to your `docker` command) to rule out any permission issue.
+
+### How do I assign an individual IP address to the container?
+
+  By default, the container uses bridge networking, which shares the IP address with the host. 
+
+  If you want to assign an individual IP address to the container, you can create a macvlan network as follows:
+
+  ```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. 
+
+  Once you have created the network, change your compose file to look as follows:
+
+  ```yaml
+  services:
+    dsm:
+      container_name: dsm
+      ..<snip>..
+      networks:
         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.
+          ipv4_address: 192.168.0.100
 
-    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.

-    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.

-    To enable this feature, add the following lines to your compose file:
+  After configuring the container for [macvlan](#how-do-i-assign-an-individual-ip-address-to-the-container), it is possible for DSM to become part of your home network by requesting an IP from your router, just like your other devices.

-    device_cgroup_rules:
-        - 'c *:* rwm'
-    ```
+  To enable this mode, in which the container and DSM will have separate IP addresses, add the following lines to your compose file:
 
-    Please note that even if you don't need DHCP, it's still recommended to enable this feature as it prevents NAT issues and increases performance by using a `macvtap` interface.

-    By default, version 7.2 will be installed, but if you prefer an older version, you can add its URL to your compose file as follows:
+  To pass-through your Intel GPU, add the following lines to your compose file:
 
-    ```yaml
-    environment:
-        URL: "https://global.synologydownload.com/download/DSM/release/7.0.1/42218/DSM_VirtualDSM_42218.pat"
-    ```
+  ```yaml
+  environment:
+    GPU: "Y"
+  devices:
+    - /dev/dri
+  ```
 
-    With this method, you are able to switch between different versions while keeping your file data.
+> [!NOTE]
+> This can be used to enable the facial recognition function in Synology Photos, but does not provide hardware transcoding for video.
 
-  * ### What are the differences compared to the standard DSM?
+### How do I install a specific version of vDSM?
 
-    There are only two minor differences: the Virtual Machine Manager package is not provided, and Surveillance Station doesn't include any free licenses.
-    
-  * ### Is this project legal?
+  By default, version 7.2 will be installed, but if you prefer an older version, you can add the download URL of the `.pat` file to your compose file as follows:
 
-    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. 
-    
-    However, by installing Synology's Virtual DSM, you must accept their end-user license agreement, which does not permit installation on non-Synology hardware. So only run this project on an official Synology NAS via the Container Manager package, as any other use will be a violation of their terms and conditions.
+  ```yaml
+  environment:
+    URL: "https://global.synologydownload.com/download/DSM/release/7.0.1/42218/DSM_VirtualDSM_42218.pat"
+  ```
 
-## Disclaimer
+  With this method, it is even possible to switch back and forth between versions while keeping your file data intact.

The product names, logos, brands, and other trademarks referred to within this project are the property of their respective trademark holders. This project is not affiliated, sponsored, or endorsed by Synology, Inc.
+  Alternatively, you can also skip the download and use a local file instead, by binding it in your compose file in this way:
+  
+  ```yaml
+  volumes:
+    - ./DSM_VirtualDSM_42218.pat:/boot.pat
+  ```

+  Replace the example path `./DSM_VirtualDSM_42218.pat` with the filename of your desired `.pat` file. The value of `URL` will be ignored in this case.

+### What are the differences compared to the standard DSM?
+
+  There are only two minor differences: the Virtual Machine Manager package is not available, and Surveillance Station will not include any free licenses.
+
+### How do I run Windows in a container?
+
+  You can use [dockur/windows](https://github.com/dockur/windows) for that. It shares many of the same features, and even has completely automatic installation.
+
+### How do I run a Linux desktop in a container?
+
+  You can use [qemus/qemu](https://github.com/qemus/qemu) in that case.
