vykulakov.github.io is supposed to be a place to store any personal notes. So this repository contains just the source code for the site.
To work with this project locally install Ruby and Bundler before. To do it on Ubuntu run the following commands:
sudo apt install ruby
sudo apt install bundler
Then go to the project directory and init the project:
bundle install
And finally, it will be possible to run a local Jekyll server:
bundle exec jekyll serve
Now you can see the site at url http://127.0.0.1:4000/
