I've just merged it, thank you for reviewing this PR.
I will update your suggestion ASAP.

@neverett Hi, will you review these docs recently?
It is really ok that you don't have time to do it.
I am thinking that we can merge this PR first since some users want this documentation to write their own agent.

[neverett]

@Future-Outlier sure thing, I can take a look today!

@Future-Outlier would it be okay if I pushed commits to this branch? I think it will be faster for me to reorganize some of the information that way.
