  Very simple! These are the steps:

-  - Set the `BOOT` variable to the [operating system](#how-do-i-select-the-operating-system) you want to install.
+  - Set the `BOOT` environment variable to the URL of any [disk image](#what-image-formats-are-supported) you want to install.

-  - Start the container and connect to [port 8006](http://127.0.0.1:8006/) using your web browser.
+  - Start the container and connect to [port 8006](http://localhost:8006) using your web browser.

  - You will see the screen and can now install the OS of your choice using your keyboard and mouse.

  Enjoy your brand new machine, and don't forget to star this repo!

-### How do I select the operating system?
-
-  You can use the `BOOT` environment variable in order to specify the operating system that will be downloaded:
-
-  ```yaml
-  environment:
-    BOOT: "alpine"
-  ```
-  Select from the values below:
-  
-  | **Value**  | **Operating System** | **Size** |
-  |---|---|---|
-  | `alma`     | Alma Linux      | 1.7 GB  |
-  | `alpine`   | Alpine Linux    | 60 MB   |
-  | `cachy`    | CachyOS         | 2.6 GB  |
-  | `centos`   | CentOS          | 6.4 GB  |
-  | `debian`   | Debian          | 3.7 GB  |
-  | `fedora`   | Fedora          | 2.9 GB  |
-  | `gentoo`   | Gentoo          | 1.3 GB  |
-  | `kali`     | Kali Linux      | 3.4 GB  |
-  | `nixos`    | NixOS           | 2.4 GB  |
-  | `suse`     | OpenSUSE        | 1.0 GB  |
-  | `oracle`   | Oracle Linux    | 1.0 GB  |
-  | `rocky`    | Rocky Linux     | 1.9 GB  |
-  | `ubuntu`   | Ubuntu Desktop  | 3.3 GB  |
-  | `ubuntus`  | Ubuntu Server   | 2.7 GB  |
-
-### How can I use my own image?
-
-  If you want to download an operating system that is not in the list above, you can set the `BOOT` variable to the URL of the image:
-
-  ```yaml
-  environment:
-    BOOT: "https://dl-cdn.alpinelinux.org/alpine/v3.19/releases/aarch64/alpine-virt-3.19.1-aarch64.iso"
-  ```
-
-  The `BOOT` URL accepts files in any of the following formats:
-
-  | **Extension** | **Format**  |
-  |---|---|
-  | `.img`        | Raw         |
-  | `.raw`        | Raw         |
-  | `.iso`        | Optical     |
-  | `.qcow2`      | QEMU        |
-  | `.vmdk`       | VMware      |
-  | `.vhd`        | VirtualPC   |
-  | `.vhdx`       | Hyper-V     |
-  | `.vdi`        | VirtualBox  |
-
-   It will also accept files such as `.img.gz`, `.qcow2.xz`, `.iso.zip` and many more, because it will automaticly extract compressed files.
-
-  Alternatively you can use a local image file directly, by binding it in your compose file:
-  
-  ```yaml
-  volumes:
-    - ./example.iso:/boot.iso
-  ```
-
-  This way you can supply either a `/boot.iso`, `/boot.img` or a `/boot.qcow2` file. The value of `BOOT` will be ignored in this case.
-
 ### How do I change the storage location?

  To change the storage location, include the following bind mount in your compose file:

  ```yaml
  volumes:
-    - ./qemu:/storage
+    - /var/qemu:/storage
  ```

-  Replace the example path `./qemu` with the desired storage folder or named volume.
-  
+  Replace the example path `/var/qemu` with the desired storage folder.
+
 ### How do I change the size of the disk?

  To expand the default size of 16 GB, add the `DISK_SIZE` setting to your compose file and set it to your preferred capacity:

 > This can also be used to resize the existing disk to a larger capacity without any data loss.

-### How do I change the amount of CPU or RAM?
-
-  By default, the container will be allowed to use a maximum of 2 CPU cores and 2 GB of RAM.
-
-  If you want to adjust this, you can specify the desired amount using the following environment variables:
-
-  ```yaml
-  environment:
-    RAM_SIZE: "8G"
-    CPU_CORES: "4"
-  ```
-
 ### How do I increase the display resolution?

  For maximum compatibility, the display output will be a simple framebuffer by default. While this isn't the most optimal, it doesn't require any drivers.

+### How do I boot a local image?
+
+  You can use a local image file directly, and skip the download altogether, by binding it in your compose file:
+  
+  ```yaml
+  volumes:
+    - /home/user/example.iso:/boot.iso
+  ```

 ### How do I boot Windows?

  Use [dockur/windows-arm](https://github.com/dockur/windows-arm) instead, as it includes all the drivers required during installation, amongst many other features.

+  You can use [qemu-docker](https://github.com/qemus/qemu-docker/) to run x86 and x64 images on ARM.
+
+### How do I boot without SCSI drivers?
+
+  By default, the machine makes use of `virtio-scsi` drives for performance reasons, and even though most Linux kernels bundle the necessary driver for this device, that may not always be the case for other operating systems.
+
+  If your machine fails to detect the hard drive, you can modify your compose file to use `virtio-blk` instead:
+
+  ```yaml
+  environment:
+    DISK_TYPE: "blk"
+  ```
+
+> [!TIP]
+> If it still fails to boot, you can set the value to `usb` to emulate a USB drive, which is slower but requires no drivers and is compatible with almost every system.
+
+### How do I change the amount of CPU or RAM?
+
+  By default, the container will be allowed to use a maximum of 1 CPU core and 1 GB of RAM.
+
+  If you want to adjust this, you can specify the desired amount using the following environment variables:
+
+  ```yaml
+  environment:
+    RAM_SIZE: "4G"
+    CPU_CORES: "4"
+  ```

 ### How do I verify if my system supports KVM?

-  First check if your software is compatible using this chart:
-
-  | **Product**  | **Linux** | **Win11** | **Win10** | **macOS** |
-  |---|---|---|---|---|
-  | Docker CLI        | ✅   | ✅       | ❌        | ❌ |
-  | Docker Desktop    | ❌   | ✅       | ❌        | ❌ |

  - you are not using a cloud provider, as most of them do not allow nested virtualization for their VPS's.

-  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.

-### How do I expose network ports?
+  - you are not using "Docker Desktop for Linux" as it does not support KVM, instead make use of Docker Engine directly.
 
-   You can expose ports just by adding them to your compose file. If you want to be able to connect to the SSH service of the machine for example, you would add it like this:
-   
-   ```yaml
-   ports:
-     - 2222:22
-   ```
- 
-   This will make port 2222 on your host redirect to port 22 of the virtual machine.
+  - it could help to add `privileged: true` to your compose file (or `sudo` to your `docker run` command), to rule out any permission issue.

 ### How do I assign an individual IP address to the container?

  After configuring the container for [macvlan](#how-do-i-assign-an-individual-ip-address-to-the-container), it is possible for the VM to become part of your home network by requesting an IP from your router, just like a real PC.

-  To enable this mode, in which the container and the VM will have separate IP addresses, add the following lines to your compose file:

 ### How do I add multiple disks?

-### How do I share files with the host?
-
-  To share files with the host, first ensure that your guest OS has `9pfs` support compiled in or available as a kernel module. If so, add the following volume to your compose file:
-
-  ```yaml
-  volumes:
-    - ./example:/shared
-  ```
-
-  Then start the container and execute the following command in the guest:
-
-  ```shell
-  mount -t 9p -o trans=virtio shared /mnt/example
-  ```
-
-  Now the `./example` directory on the host will be available as `/mnt/example` in the guest.

 ### How can I provide custom arguments to QEMU?

  You can create the `ARGUMENTS` environment variable to provide additional arguments to QEMU at runtime:

+### What image formats are supported?

+  | **Extension** | **Format**   |
+  |---|---|
+  | `.img`       | Raw           |
+  | `.raw`       | Raw           |
+  | `.iso`        | Optical       |
+  | `.qcow2` | QEMU         |
+  | `.vmdk`   | VMware      |
+  | `.vhd`       | VirtualPC   |
+  | `.vhdx`     | Hyper-V     |
+  | `.vdi`        | VirtualBox |
+
+  > [!TIP]
+> It will also accept `.img.gz`, `.qcow2.xz`, `.iso.zip` and many more, as it automaticly extracts compressed files.
