-Apertis is built as a few different system images:
-
-  - *Target*: contains core OS plus middleware ready to be used as a
-    base for other applications.
-  - *Development*: Contains target image plus development tools and
-    debugging libraries.
-  - *SDK*: Contains development image plus XFCE4 and Eclipse
-    environment.
-
-These various images can be found at [1](https://images.apertis.org/)
-
-Instructions on how to setup the various type of images follows below.
-
-## Target images
-
-Target and Development images can be used in virtualbox or on intel
-hardware. This section handles only installation directly on hardware.
-For installation in virtualbox, the same steps as for the SDK image can
-be used with the target or development VDI image.
-
-For use on hardware the `*img.gz` should be used and should be written
-to an SD card or USB stick for booting on the target hardware. After
-retrieving an image it can be written to an SD card as follows (assuming
-*/dev/mmcblk0* is your first SD card):
-
-` $ zcat apertis-15.06...img.gz | sudo dd of=/dev/mmcblk0 bs=8192`
-
-## SDK Images
-
-Retrieve the latest `*.vdi.gz` compressed VirtualBox disk image from the
-[SDK image directory](https://images.apertis.org/).
-
-Once downloading completes, decompress the archive. This will leave you
-with a `*.vdi` disk image.
-
-### Step 0: Install VirtualBox
-
-Some features such as the integrated webcam require the last version
-4.3.2. The packages are available on [the VirtualBox
-website](https://www.virtualbox.org/wiki/Downloads).
-
-  - Install VirtualBox 4.3.2
-  - Install Oracle VM VirtualBox Extension Pack
-
-In the menu **File**, **Preferences**, check that the extension is
-correctly installed:
-
-![<File:00-virtualbox-extensions.png>](/images/00-virtualbox-extensions.png)
-
-### Step 1: Create a new virtual machine
-
-Open VirtualBox and click the **New** button to create a new virtual
-machine.
-
-![<File:01-new-machine.png>](/images/01-new-machine.png)
-
-Click **next**.
-
-### Step 2: Name the machine
-
-Provide a name for the new machine. We recommend including the date of
-the image in case you create another SDK machines before deleting the
-first.
-
-Set the **Operating System** to Linux and **Version** to Ubuntu.
-
-![<File:02-name-machine.png>](/images/02-name-machine.png)
-
-Click **next**.
-
-### Step 3: Set the memory allocation
-
-Set the amount of memory to be allocated to this machine. We recommend
-at least 2048 MB.
-
-![<File:03-set-memory.png>](/images/03-set-memory.png)
-
-Click **next**.
-
-### Step 4: Select disk image and create
-
-Click **Use existing hard disk** and the "select disk" button
-(highlighted in the image below).
-
-![<File:04-select-disk.png>](/images/04-select-disk.png)
-
-Select the `*.vdi` disk image from before and click **Open**.
-
-Click **next**. Click **Create**.
-
-### Step 5: Configure CPUs
-
-Locate the new machine on the left side of the main VirtualBox window.
-Right-click on it and select **Settings**.
-
-Click **System** on the left side, then the **Processor** tab. Set the
-number of CPUs to 4 and ensure that the Execution Cap is 100(%).
-
-![<File:05-set-cpus.png>](/images/05-set-cpus.png)
-
-### Step 6: Configure Display
-
-Click **Display** on the left side, then the **Video** tab. Set the
-**Video Memory** to at least 12 MB.
-
-Ensure that "Enable 3D Acceleration" and "Enable 2D Video Acceleration"
-are both **unchecked** as they can interfere with proper graphics
-operation within the SDK.
-
-![<File:06-display-settings.png>](/images/06-display-settings.png)
-
-Click **OK**.
-
-### Step 7: Running machine and default desktop setup
-
-In main VirtualBox window, double-click the name of the new machine. It
-will open in a new window and boot the SDK.
-
-Once booting is complete, you will see a desktop.
-
-If prompted to select a desktop setup, choose **Use default config**
-
-![<File:07-default-config.png>](/images/07-default-config.png)
-
-The final desktop will look similar to the following image:
-
-![<File:08-sdk-desktop.png>](/images/08-sdk-desktop.png)
-
-### Step 8: Installing the guest extensions
-
-In the menu **Devices**, choose **Insert Guest Additions CD image...**:
-
-![<File:09-virtualbox-guest-additions.png>](/images/09-virtualbox-guest-additions.png)
-
-The CD will be mounted in the virtual image. Then, as root:
-
-`# /media/user/VBOXADDITIONS_4.3.2_90405/VBoxLinuxAdditions.run`
-
-### Step 9: Misc devices
-
-  - Webcam: the webcam works better when used through the VirtualBox
-    integrated webcam rather than through USB.
-      - Make sure USB WebCam is not assigned as "normal" USB device to
-        VirtualBox: disable it in menu **Machine** -\> **Settings** -\>
-        **USB**
-      - Enable the webcam with menu **Devices** -\> **Webcams** -\>
-        **integrated webcam**
-
-<!-- end list -->
-
-  - Bluetooth USB dongle: the USB device is plugged on the host but it
-    can be made available to the VM through a VirtualBox USB filter:
-    menu **Machine** -\> **Settings** -\> **USB**. Beware, a single
-    device could have several ProductId: example with an Asus USB-BT211:
-
-` `<code>`# lsusb # before the firmware is loaded`
-` 0cf3:3000 Atheros Communications, Inc. AR3011 Bluetooth (no firmware)`
-` # lsusb # after the firmware is loaded`
-` 0cf3:3005 Atheros Communications, Inc. AR3011 Bluetooth`</code>
-
-Therefore, you might have to change the VirtualBox USB filter to let
-them all go to the VM by removing the ProductId:
