Broken link

1 Open link file:///C:/Program%20Files/Unity%205.0.0b21/Editor/Data/Documentation/en/Manual/FBXImporter-Rig.html
it has text:
"If you have a non humanoid character e.g. a quadruped, or any animateable entity that you wish to use with Mecanim choose Generic. After choosing you will then need to identify a bone in the drop down to use as the root node."
2 and click on Mecanim word with link

Actual result: the link is broken

And in this text word "animateable" should be "animatable"
