 ## FAQ
 
-  * ### How do I change the size of the virtual disk?
+* ### How do I use it?
 
-    To expand the default size of 16 GB, locate the `DISK_SIZE` setting in your compose file and modify it to your preferred capacity:
+  Very simple! These are the steps:
+  
+  - Start the container and connect to [port 5000](http://localhost:5000) using your web browser.
 
-    ```yaml
-    environment:
-      DISK_SIZE: "128G"
-    ```
-    
-    This can also be used to resize the existing disk to a larger capacity without any data loss. 
+  - Wait until DSM is ready, choose an username and password, and you will be taken to the desktop.
+  
+  Enjoy your brand new machine, and don't forget to star this repo!

-    To change the virtual disk's location from the default Docker volume, include the following bind mount in your compose file:
+  To expand the default size of 16 GB, locate the `DISK_SIZE` setting in your compose file and modify it to your preferred capacity:
 
-    ```yaml
-    volumes:
-      - /home/user/data:/storage
-    ```
+  ```yaml
+  environment:
+    DISK_SIZE: "128G"
+  ```
+  
+  This can also be used to resize the existing disk to a larger capacity without any data loss. 
 
-    Replace the example path `/home/user/data` with the desired storage folder.
+* ### How do I change the storage location?
 
-  * ### How do I add multiple disks?
+  To change the storage location, include the following bind mount in your compose file:
 
-    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
-    ```
+  ```yaml
+  volumes:
+    - /var/dsm:/storage
+  ```
 
-  * ### How do I change the space reserved by the virtual disk? 
+  Replace the example path `/var/dsm` with the desired storage folder.
 
-    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:
+* ### How do I create a growable disk?
 
-    ```yaml
-    environment:
-      ALLOCATE: "N"
-    ```
+  By default, the entire capacity of the disk is reserved in advance.
 
-    Keep in mind that this will not affect any of your existing disks, it only applies to newly created disks.
+  To create a growable disk that only allocates space that is actually used, add the following environment variable:
 
-  * ### How do I increase the amount of CPU or RAM?
+  ```yaml
+  environment:
+    DISK_FMT: "qcow2"
+  ```
 
-    By default, a single core and 1 GB of RAM are allocated to the container. To increase this, add the following environment variables:
+  Please note that this may reduce the write performance of the disk.
 
-    ```yaml
-    environment:
-      RAM_SIZE: "4G"
-      CPU_CORES: "4"
-    ```
+* ### How do I add multiple disks?
 
-  * ### How do I verify if my system supports KVM?
+  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 verify if your system supports KVM, run the following commands:
+* ### How do I pass-through a disk?
 
-    ```bash
-    sudo apt install cpu-checker
-    sudo kvm-ok
-    ```
+   It is possible to pass-through disk devices directly by adding them to your compose file in this way:
 
-    If you receive an error from `kvm-ok` indicating that KVM acceleration can't be used, check your BIOS settings.
+  ```yaml
+  environment:
+    DEVICE2: "/dev/sda"
+    DEVICE3: "/dev/sdb"
+  devices:
+    - /dev/sda
+    - /dev/sdb
+  ```
 
-  * ### How do I assign an individual IP address to the container?
+  Please note that the device needs to be totally empty (without any partition table) otherwise DSM does not always format it into a volume.
 
-    By default, the container uses bridge networking, which shares the IP address with the host. 
+  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.
 
-    If you want to assign an individual IP address to the container, you can create a macvlan network as follows:
+* ### How do I increase the amount of CPU or RAM?
 
-    ```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. 
+  By default, a single CPU core and 1 GB of RAM are allocated to the container.
 
-    Once you have created the network, change your compose file to look as follows:
+  To increase this, add the following environment variables:
 
-    ```yaml
-    services:
-      dsm:
-        container_name: dsm
-        ..<snip>..
-        networks:
-          vdsm:
-            ipv4_address: 192.168.0.100
+  ```yaml
+  environment:
+    RAM_SIZE: "4G"
+    CPU_CORES: "4"
+  ```
 
-    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.

-    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.
+  To verify if your system supports KVM, run the following commands:
 
-  * ### How can the container acquire an IP address from my router?
+  ```bash
+  sudo apt install cpu-checker
+  sudo kvm-ok
+  ```
 
-    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.
+  If you receive an error from `kvm-ok` indicating that KVM acceleration can't be used, check the virtualization settings in the BIOS.
 
-    To enable this feature, add the following lines to your compose file:
+* ### How do I assign an individual IP address to the container?
 
-    ```yaml
-    environment:
-      DHCP: "Y"
-    devices:
-      - /dev/vhost-net
-    device_cgroup_rules:
-      - 'c *:* rwm'
-    ```
+  By default, the container uses bridge networking, which shares the IP address with the host. 
 
-    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.
+  If you want to assign an individual IP address to the container, you can create a macvlan network as follows:
 
-  * ### How do I passthrough the GPU?
+  ```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. 
 
-    To passthrough your Intel GPU, add the following lines to your compose file:
+  Once you have created the network, change your compose file to look as follows:
 
-    ```yaml
-    environment:
-      GPU: "Y"
-    devices:
-      - /dev/dri
-    ```
+  ```yaml
+  services:
+    dsm:
+      container_name: dsm
+      ..<snip>..
+      networks:
+        vdsm:
+          ipv4_address: 192.168.0.100
 
-    This can be used to enable the facial recognition function in Synology Photos for example.
+  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.
 
-  * ### How do I install a specific version of vDSM?
+  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.
 
-    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:
+* ### How can DSM acquire an IP address from my router?
 
-    ```yaml
-    environment:
-      URL: "https://global.synologydownload.com/download/DSM/release/7.0.1/42218/DSM_VirtualDSM_42218.pat"
-    ```
+  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.
 
-    With this method, it is even possible to switch between different versions while keeping all your file data intact.
+  To enable this mode, add the following lines to your compose file:
 
-  * ### What are the differences compared to the standard DSM?
+  ```yaml
+  environment:
+    DHCP: "Y"
+  devices:
+    - /dev/vhost-net
+  device_cgroup_rules:
+    - 'c *:* rwm'
+  ```
 
-    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?
+  Please note that even if you don't need DHCP, it's still recommended to enable this mode, as it prevents NAT issues and increases performance by using a `macvtap` interface. You can just set a static IP from the DSM control panel afterwards.
 
-    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?
+
+  To pass-through your Intel GPU, add the following lines to your compose file:

+    - /dev/dri
