Setting up a character for mecanim?

So i’ve never used mecanim before, but it seems like it’s the way to go, so I’ve decided to try it out. But I’ve been having some issues, and I think it’s mainly with the way my characters are setup.

I model them in blender, but is there something I should do to get them to work properly with mecanim? Like should I set up a rig in blender a certain way? Or how should the character be for it to work properly?

Thanks

This page should answer your question and then some: Automatic Setup of a Humanoid | Unity Blog

It explains what bones you need, how they should be oriented, how they’re interpreted, etc.
