+GoVPN is written on @url{https://golang.org/, Go} programming language
+and you have to install Go compiler (1.5+ version is highly recommended,
+1.4 is the minimal sufficient): @code{lang/go} port in FreeBSD and
+@code{golang} package in most GNU/Linux distributions. @emph{Make} (BSD
+and GNU ones are fine) is recommended for convenient building.
+@url{https://www.gnu.org/software/texinfo/, Texinfo} (6.1+ version is
+recommended) is used for building documentation. Possibly you also need
+to install TUN/TAP interface utilities (depending on your operating
+system): @command{uml-utilities} package in most GNU/Linux distributions.
+
+Get @ref{Tarballs, the tarball}, check its
+@ref{Integrity, integrity and authenticity} and run @command{make}.
