@liangyuanpeng Mentor, where do you think it would be a better choice to place the supplementary configuration file documentation? I observed that in the Reference sidebar, there are two options: Command line tool (karmadactl) and karmada API. Currently, I have placed the documentation for this configuration file under Command line tool (karmadactl). Do you think this is the better choice, or would it be better placed elsewhere?

I recommend to add to https://karmada.io/docs/installation, WDYT? @XiShanYongYe-Chang
