there is existing theme on github pages, how can I replace jekyll-theme?

I forked some jekyll themes. So I have github io remote on my git account, now. However, I want to replace another theme. is it possible to change?

Solution

Yes, it is possible to use custom Jekyll themes.

To build your site with any public, GitHub-hosted theme, add the following to your site’s _config.yml file:

remote_theme: owner/name

Replacing owner and name with the repository’s owner and name.
