 ### How do I use it?
 
   Very simple! These are the steps:
   
-  - Start the container and connect to [port 5000](http://localhost:5000) using your web browser.
+  - Start the container and connect to [port 5000](http://127.0.0.1:5000/) using your web browser.
 
-  - Wait until DSM is ready, choose an username and password, and you will be taken to the desktop.

-  Replace the example path `/var/dsm` with the desired storage folder.
+  Replace the example path `./dsm` with the desired storage folder or named volume.
  
 ### How do I change the size of the disk?
 
-  To expand the default size of 16 GB, locate the `DISK_SIZE` setting in your compose file and modify it to your preferred capacity:
+  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:
-    DISK_SIZE: "128G"
+    DISK_SIZE: "512G"
   ```
   
 > [!TIP]
 > This can also be used to resize the existing disk to a larger capacity without any data loss.
 
-### How do I create a growable disk?
-
-  By default, the entire capacity of the disk is reserved in advance.
-
-  To create a growable disk that only allocates space that is actually used, add the following environment variable:
-
-  ```yaml
-  environment:
-    DISK_FMT: "qcow2"
-  ```
-
-> [!NOTE]
-> This may reduce the write performance of the disk.
-
 ### How do I add multiple disks?
 
   To create additional disks, modify your compose file like this:
   
   ```yaml
   environment:
-    DISK2_SIZE: "32G"
+    DISK2_SIZE: "500G"
-    DISK3_SIZE: "64G"
+    DISK3_SIZE: "750G"
   volumes:
-    - /home/example:/storage2
+    - ./example2:/storage2
-    - /mnt/data/example:/storage3
+    - ./example3:/storage3
   ```
 
 ### How do I pass-through a disk?
 
-   It is possible to pass-through a disk device directly, by adding it to your compose file in this way:
+   It is possible to pass-through disk devices or partitions directly by adding them to your compose file in this way:
 
   ```yaml
   devices:
-    - /dev/disk/by-uuid/12345-12345-12345-12345-12345:/disk2
+    - /dev/sdb:/disk1
+    - /dev/sdc1:/disk2
   ```
 
-  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. 
+  Make sure it is totally empty (without any filesystem), otherwise DSM may not format it as a volume.
-
-> [!IMPORTANT]
-> The device needs to be totally empty (without any partition table) otherwise DSM does not always format it into a volume.
-
-> [!CAUTION]
-> 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.

-  To verify that your system supports KVM, run the following commands:
+  First check if your software is compatible using this chart:
+
+  | **Product**  | **Linux** | **Win11** | **Win10** | **macOS** |
+  |---|---|---|---|---|
+  | Docker CLI        | ✅   | ✅       | ❌        | ❌ |

+  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 are running an operating system that supports them, like Linux or Windows 11 (macOS and Windows 10 do not unfortunately).
-
   - 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 didn't receive any error from `kvm-ok` at all, but the container still complains that `/dev/kvm` is missing, it might help to add `privileged: true` to your compose file (or `--privileged` to your `run` command), to rule out any permission issue.
