+  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"

 > [!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 will be 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"

 ### How do I add multiple disks?
 
   To create additional disks, modify your compose file like this:

-### 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.

 ### 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.
