Aditu is a stylish and modern dark theme with a clean and unique design, this theme is created for those who want to share their stories quickly and easily, as well as provide your readers with an unforgettable experience of viewing content.
To run the theme locally, navigate to the theme directory and run bundle install to install the dependencies, then run bundle exec jekyll serve to start the Jekyll server.
I would recommend checking the Deployment Methods page on Jekyll website.
