Hi guys, would you be available to review this problem, I have given a solution to this issue #861.

Thanks for the consideration. Please let me know if you have any other questions.

This actually doesn't work at all.

using:

window.$docsify = {
 name: "",
 repo: "",
 loadSidebar: "summary.md"
 };

...simply does nothing. Even setting it to false doesn't get rid of the sidebar. Kind of sad that the owner doesn't seem to care because this renders their project useless since you can't even get rid of the useless sidebar.

Lame.
