+You need to install [VirtualBox](#https://www.virtualbox.org/wiki/Downloads)
+next to [Vagrant for Windows](#http://www.vagrantup.com/downloads.html). For SSH access
+you need to install [Git for Windows](#http://git-scm.com/download/win) too.
+
+Either download and extract the Icinga 2 tarball (or git archive) or clone the
+git repository using your preferred git gui.
+
+Open the Windows command prompt (cmd+R) and change the directory to your
+Icinga 2 directory containing the `Vagrantfile` file and start the Vagrant box.
+
+    c:> cd C:\Users\admin\icinga2
+    c:> vagrant up
+
+> **Note**
+>
+> If SSH access is not working, you may need to add the Git binary path to the system path.
+
+    c:> set PATH=%PATH%;C:\Program Files (x86)\Git\bin
+    c:> vagrant ssh
+
+For manual SSH access using [Putty](#http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html)
+you'll need the following default credentials:
+
+  Name            |Value

+  hostname        | 127.0.0.1
