+Preparing the Gitian builder host
+---------------------------------
+
+The first step is to prepare the host environment that will be used to perform the Gitian builds.
+In this guide it is explained how to set up the environment, and how to get the builds started.
+
+Debian Linux was chosen as the host distribution because it has a lightweight install (in contrast to Ubuntu) and is readily available.
+Any kind of virtualization can be used, for example:
+- [VirtualBox](https://www.virtualbox.org/), covered by this guide
+- [KVM](http://www.linux-kvm.org/page/Main_Page)
+- [LXC](https://linuxcontainers.org/), see also [Gitian host docker container](https://github.com/gdm85/tenku/tree/master/docker/gitian-bitcoin-host/README.md).
+
+You can also install on actual hardware instead of using virtualization.
