[arch-general] Download wiki arch!

Hello, I've begun to use arch instead of Ubuntu, and it seems great, especially the (wiki.archlinux.org); but it is only available online, and I am in need of an offline source with such rich information, I did some googling, but all I get is how to download Wikipedia, or using of websucker.. So, is there anyway I can download wiki.archlinux.org, or anything equivalent? Any advice would be appreciated! Best regards.
