@Phoenix500526 is their any order in which a particular arguments needed to be shown, like right now --client-listen-urlsand --peer-listen-urls are first and then rest of the flags, i will change if required. While playing with Xline, i found a small ip-address issue with the quick_start.sh script for prometheus and quick-start DOC. Should i raise a issue for this or are we going to change the quick_start soon in this issue https://github.com/xline-kv/Xline/issues/692.

Is the issue you mentioned above described in issue #692? If not, I think it's better to initiate a new issue to describe it.
