+- guest managed by [Vagrant](https://www.vagrantup.com/). This uses Virtualbox (as above) but does so in an easily repeatable way. Please check the [Armbian with Vagrant README](https://docs.armbian.com/Developer-Guide_Using-Vagrant/) for a quick start HOWTO,
+- inside a [Docker](https://www.docker.com/), [systemd-nspawn](https://www.freedesktop.org/software/systemd/man/systemd-nspawn.html) or other container environment [(example)](https://github.com/armbian/build/pull/255#issuecomment-205045273),
+- running natively on a dedicated PC or a server (**not** recommended),
+- **20GB disk space** or more and **2GB RAM** or more available for the VM, container or native OS,
+- superuser rights (configured `sudo` or root access).
+
+**Execution**
+
+	apt-get -y install git
+	git clone https://github.com/armbian/build
+	cd build
+	./compile.sh
+
+Make sure that full path to the build script does not contain spaces.
+
+You will be prompted with a selection menu for a build option, a board name, a kernel branch and an OS release. Please check the documentation for [advanced options](https://docs.armbian.com/Developer-Guide_Build-Options/) and [additional customization](https://docs.armbian.com/Developer-Guide_User-Configurations/).

+Build process uses caching for the compilation and the debootstrap process, so consecutive runs with similar settings will be much faster.

 This is a basic guide to help you setting up Helios4 NAS with [OpenMediaVault](https://www.openmediavault.org/) (**OMV**). OMV offers a large collection of features that we don't cover here. We invite you to look online for the existing OMV guides or go on the [OMV forum](https://forum.openmediavault.org/index.php/Board/29-Guides/).
 
+!!! info
+    The following guide was written for OMV3 (OpenMediaVault 3.X). It should still apply to OMV4.

 ## What is OpenMediaVault?
 
 OpenMediaVault (OMV) is a next-gen network attached storage (NAS) software based on Debian Linux. It contains services like SSH, (S)FTP, SMB/CIFS, DAAP media server, RSync, BitTorrent client and many more... all configurable via a Web Control Panel. Thanks to a modular framework design, new features can be added to OMV via plugins. It is a simple and easy to use out-of-the-box solution that will allow everyone to install and administrate a Network Attached Storage without deeper knowledge.
 
+## Install Openmediavault
+
+You can easily install OMV with the **armbian-config** tool.
+
+!!! note
+    If you have installed a pre-built OpenMediaVault image you can skip this step.
+
+Connect to your Helios4 via SSH as explained [here](/install/#step-7-connect-to-helios4-via-ssh).
+
+Launch **armbian-config** and follow the steps.
+
+```bash
+sudo armbian-config
