Links to Galaxy documentation are broken

[iay]

The update to Galaxy NG has broken some links.

Example, reference 72 (page 144 in edition 2.2):

see the official documentation: Installing Multiple Roles From a File.

This no longer leads anywhere useful. I'd suggest a replacement destination, but the new documentation has me befuddled and I haven't really found something equivalent.

Definitely needs to get fixed, but I think part of the NG move was a bit of cleaning house and dumping a lot of roles documentation specifically. Or at least shifting it around so much and making Collections more prominent :(
