-  * ### 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: "128G"
-    ```
-    
-    This can also be used to resize the existing disk to a larger capacity without any data loss. 
+[![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 location of the virtual disk, include the following bind mount in your compose file:
+### How do I use it?
 
-    ```yaml
-    volumes:
-      - /var/dsm:/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 `/var/dsm` 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 add multiple disks?
+### How do I change the storage location?
 
-    To create additional disks, modify your compose file like this:
-    
-    ```yaml
-    environment:
-      DISK2_SIZE: "32G"
-      DISK3_SIZE: "64G"
-    volumes:
-      - /home/example:/storage2
-      - /mnt/data/example:/storage3
-    ```
+  To change the storage location, include the following bind mount in your compose file:
 
-  * ### How do I create a growable disk?
+  ```yaml
+  volumes:
+    - ./dsm:/storage
+  ```
 
-    By default, the entire capacity of the disk is reserved in advance.
+  Replace the example path `./dsm` with the desired storage folder or named volume.
+ 
+### How do I change the size of the disk?
 
-    To create a growable disk that only allocates space that is actually used, add the following environment variables:
+  To expand the default size of 256 GB, locate the `DISK_SIZE` setting in your compose file and modify it to your preferred capacity:
 
-    ```yaml
-    environment:
-      ALLOCATE: "N"
-      DISK_FMT: "qcow2"
-    ```
+  ```yaml
+  environment:
+    DISK_SIZE: "512G"
+  ```
+  
+> [!TIP]
+> This can also be used to resize the existing disk to a larger capacity without any data loss.
 
-    Please note that this may reduce the write performance of the disk.
+### How do I add multiple disks?
 
-  * ### How do I increase the amount of CPU or RAM?
+  To create additional disks, modify your compose file like this:
+  
+  ```yaml
+  environment:
+    DISK2_SIZE: "500G"
+    DISK3_SIZE: "750G"
+  volumes:
+    - ./example2:/storage2
+    - ./example3:/storage3
+  ```
 
-    By default, a single core and 1 GB of RAM are allocated to the container.
+### How do I pass-through a disk?
 
-    To increase this, add the following environment variables:
+   It is possible to pass-through disk devices or partitions directly by adding them to your compose file in this way:
 
-    ```yaml
-    environment:
-      RAM_SIZE: "4G"
-      CPU_CORES: "4"
-    ```
+  ```yaml
+  devices:
+    - /dev/sdb:/disk1
+    - /dev/sdc1:/disk2
+  ```
 
-  * ### How do I verify if my system supports KVM?
+  Make sure it is totally empty (without any filesystem), otherwise DSM may not format it as a volume.
 
-    To verify if your system supports KVM, run the following commands:
+### How do I change the amount of CPU or RAM?
 
-    ```bash
-    sudo apt install cpu-checker
-    sudo kvm-ok
-    ```
+  By default, Virtual DSM will be allowed to use 2 CPU cores and 2 GB of RAM.
 
-    If you receive an error from `kvm-ok` indicating that KVM acceleration can't be used, check your BIOS settings.
+  If you want to adjust this, you can specify the desired amount using the following environment variables:
 
-  * ### How do I assign an individual IP address to the container?
+  ```yaml
+  environment:
+    RAM_SIZE: "4G"
+    CPU_CORES: "4"
+  ```
 
-    By default, the container uses bridge networking, which shares the IP address with the host. 
+### How do I verify if my system supports KVM?
 
-    If you want to assign an individual IP address to the container, you can create a macvlan network as follows:
+  First check if your software is compatible using this chart:
 
-    ```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. 
+  | **Product**  | **Linux** | **Win11** | **Win10** | **macOS** |
+  |---|---|---|---|---|
+  | Docker CLI        | ✅   | ✅       | ❌        | ❌ |
+  | Docker Desktop    | ❌   | ✅       | ❌        | ❌ |

+  | Podman Desktop    | ✅   | ✅       | ❌        | ❌ | 
 
-    Once you have created the network, change your compose file to look as follows:
+  After that you can run the following commands in Linux to check your system:
 
-    ```yaml
-    services:
-      dsm:
-        container_name: dsm
-        ..<snip>..
-        networks:
-          vdsm:
-            ipv4_address: 192.168.0.100
+  ```bash
+  sudo apt install cpu-checker
+  sudo kvm-ok
+  ```
 
-    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.
+  If you receive an error from `kvm-ok` indicating that KVM cannot be used, please check whether:
 
-    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.
+  - the virtualization extensions (`Intel VT-x` or `AMD SVM`) are enabled in your BIOS.
 
-  * ### How can the container acquire an IP address from my router?
+  - you enabled "nested virtualization" if you are running the container inside a virtual machine.
 
-    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.
+  - you are not using a cloud provider, as most of them do not allow nested virtualization for their VPS's.
 
-    To enable this feature, add the following lines to your compose file:
+  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.
 
-    ```yaml
-    environment:
-      DHCP: "Y"
-    device_cgroup_rules:
-      - 'c *:* rwm'
-    ```
+### How do I assign an individual IP address to the container?
 
-    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.
+  By default, the container uses bridge networking, which shares the IP address with the host. 
 
-  * ### How do I passthrough the GPU?
+  If you want to assign an individual IP address to the container, you can create a macvlan network as follows:
 
-    To passthrough your Intel GPU, add the following lines to your compose file:
+  ```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
-    environment:
-      GPU: "Y"
-    devices:
-      - /dev/dri
-    ```
+  Once you have created the network, change your compose file to look as follows:
 
-    This can be used to enable the facial recognition function in Synology Photos for example.
+  ```yaml
+  services:
+    dsm:
+      container_name: dsm
+      ..<snip>..
+      networks:
+        vdsm:
+          ipv4_address: 192.168.0.100
 
-  * ### How do I install a specific version of vDSM?
+  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.
 
-    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:
+> [!IMPORTANT]
+> 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:
-      URL: "https://global.synologydownload.com/download/DSM/release/7.0.1/42218/DSM_VirtualDSM_42218.pat"
-    ```
+### How can DSM acquire an IP address from my router?
 
-    With this method, it is even possible to switch between different versions while keeping all your file data intact.
+  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.
 
-  * ### What are the differences compared to the standard DSM?
+  To enable this mode, in which the container and DSM will have separate IP addresses, add the following lines to your compose file:
 
-    There are only two minor differences: the Virtual Machine Manager package is not available, and Surveillance Station will not include any free licenses.
-    
-  * ### Is this project legal?
+  ```yaml
+  environment:
+    DHCP: "Y"
+  devices:
+    - /dev/vhost-net
+  device_cgroup_rules:
+    - 'c *:* rwm'
+  ```
 
-    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, as any other use will be a violation of their terms and conditions.
+### How do I pass-through the GPU?
 
-## Disclaimer
+  To pass-through your Intel GPU, add the following lines to your compose file:
 
-Only run this container on Synology hardware, any other use is not permitted by their EULA. The product names, logos, brands, and other trademarks referred to within this project are the property of their respective trademark holders.

+
+### How do I install a specific version of vDSM?
+
+  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:
+
+  ```yaml
+  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 back and forth between versions while keeping your file data intact.
+
+  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.
+
+### Is this project legal?
+
+  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 will 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 container on an official Synology NAS, as any other use will be a violation of their terms and conditions.
