Getting Started With Mixamo: Auto-Rig and Animate a Character Without Hand-Weighting a Single Bone
Mixamo is Adobe's free web-based auto-rigging and animation service: upload a humanoid character, mark a few joint positions, and it returns a fully rigged, weighted mesh plus access to a library of mocap animations you can retarget onto it. This walks through the upload-to-export pipeline, where it breaks down, and when hand-rigging in Blender is still the better call.
