I followed the online documentation on how to install using the iso image and boot from CD. Since my university requires a proxy server, I have set it by configuring /etc/wget/wgetrc, which is documented in the guide. Works fine until 'emerge system' causes wget to be reinstalled and the config file got over-written. You may want to consider asking the user to export the parameters instead. Also, there is no documentation on how to set proxy_user and proxy_passwd, which may be needed by some proxy server.
I fixed this in the new install guide. //ZhEN
