The Rig tab allows you to assign or create an avatar definition to your imported skinned model so that you can animate it - see Asset Preparation and Import
If you have a humanoid character e.g. a biped (two legs) that has two arms and a head, then choose Humanoid and 'Create from this model' an Avatar will be created to best match the bone hierarchy - see Avatar Creation and Setup or you can pick an alternative avatar Definition that has already been set up.
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 choose as the root node.
Choose legacy if you wish to use the legacy animation system and import and use animations as with 3.x
