Documentation Decoder

Many different Yocto Project documentation pages are returned by Google searches and it can be hard to know what's what. URLs have the following format: http://www.yoctoproject.org/docs/release/name/name.html. Here is an example for the quick start guide for release 2.1: http://www.yoctoproject.org/docs/2.1/yocto-project-qs/yocto-project-qs.html Note that current can be used in place of the current release number.
