 ## FAQ

-  * ### How do I change the size of the virtual disk?
+  * ### How do I use it?
+
+    Very simple! These are the steps:
+    
+    - Start the container and get some coffee.
+
+    - Connect to port 5000 of the container in your web browser.
+
+    - 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!
+
+  * ### 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:

    ```yaml
    environment:
-      DISK_SIZE: "256G"
+      DISK_SIZE: "128G"
    ```
    
    This can also be used to resize the existing disk to a larger capacity without any data loss. 

-  * ### How do I change the location of the virtual disk?
+  * ### How do I change the storage location?

-    To change the virtual disk's location from the default Docker volume, include the following bind mount in your compose file:
+    To change the storage location, include the following bind mount in your compose file:

    ```yaml
    volumes:
-      - /home/user/data:/storage
+      - /var/dsm:/storage
    ```

-    Replace the example path `/home/user/data` with the desired storage folder.
+    Replace the example path `/var/dsm` with the desired storage folder.

-  * ### How do I change the space reserved by the virtual disk? 
+  * ### How do I create a growable disk?

-    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:
+    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:
-      ALLOCATE: "N"
+      DISK_FMT: "qcow2"
    ```

-    Keep in mind that this will not affect any of your existing disks, it only applies to newly created disks.
+    Please note that this may reduce the write performance of the disk.

-    Additionally, it's also possible to passthrough raw disk devices like this:
+  * ### How do I pass-through a disk?
+
+    It is possible to pass-through disk devices directly by adding them to your compose file in this way:

    ```yaml

-      DEVICE2: "/dev/vdc1"
-      DEVICE3: "/dev/vdc2"

    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.
