GitLab custom wiki sidebar not working

Question

1. I "pulled" the wiki repository of my project.
2. Created "_sidebar.md" file.
3. Git add
4. Git commit
5. Pushed the changes to GitLab.
6. Loaded the Wiki page of my project in Google Chrome's incognito mode.
7. Custom sidebar is not rendered.

I refreshed many times. No luck.

This is the content of my _sidebar.md:

0. [Home](home)
1. [Page 1](page-1)
2. [Page 2](page-2)

Any ideas?

Answer 1

It works now as VonC explained. However, you don't need to clone your repository.

Simply create a new page on GitLab GUI called _sidebar. You may access it by your-repository/wikis/_sidebar or create an edit link in your sidebar:

0. [Home](home)
1. [Page 1](page-1)
2. [Page 2](page-2)

[Edit sidebar](/_sidebar/edit)
