 Quick Build Steps for NetSurf
 =============================
 
-Last Updated: 15th December 2017
+Last Updated: 21st January 2020
 
 This document provides steps for building NetSurf.
 
+These instructions use a shell script to perform several operations.
+This script has only been tested with the bash and zsh bourne style
+shell interpreters. The latest version of this script should be
+retrieved from the official NetSurf source repository.
+
+This shell script is used by the NetSurf Developers but you should
+satisfy yourself that the script is not malicious. It should be noted
+that the building the browser will also be executing shell code and
+requires a similar level of trust.
