+If only need to build binaries for the platform you're running (Windows, Linux,
+Mac OS X etc..), you can follow the instructions in the README for [Developing
+Terraform][1].
+
+The guide below outlines the steps HashiCorp takes to build the official release 
+binaries for Terraform. This process will generate a set of binaries for each supported
+platform, using the [gox](https://github.com/mitchellh/gox) tool.
+
+A Vagrant virtual machine is used to provide a consistent envirornment with
+the pre-requisite tools in place. The specifics of this VM are defined in the 
+[Vagrantfile](Vagrantfile).

 ```sh
+# clone the repository if needed
+git clone https://github.com/hashicorp/terraform.git
+cd terraform
+
 # Spin up a fresh build VM
 vagrant destroy -f
 vagrant up
 vagrant ssh
+
+# The Vagrantfile installs Go and configures the $GOPATH at /opt/gopath
+# The current "terraform" directory is then sync'd into the gopath
 cd /opt/gopath/src/github.com/hashicorp/terraform/
