# What does this PR do?
According to DeepSpeed docs and maintainer confirmation in https://github.com/deepspeedai/DeepSpeed/issues/2721,

the aio section should NOT be included under zero_optimization, but is included in huggingface docs.

This PR fixes docs.

(I noticed that another language version of this doc is also problematic. I would just fix it anyway.)
